Aside from installation, download and other things, there's not much talk about the update itself. I found that it did a good job with a lot of things, including ones that weren't explicitly mentioned. Things were considerably better for me after the prior update that added hands free, before which the car constantly claimed that it could not recognize that I was paying attention. After that update, it could recognize me if I tilted the steering wheel down so far that I couldn't read the top of the display. After this update, the car seems to be able to see me fine, even with the steering wheel in what I'd call a normal position.
Another big change is that it no longer penalizes me for looking in the side view mirrors before a lane change. It used to change the dashed lines to solid if I looked away long enough to see if things were clear. I can now make sure that things are clear and then turn on the signal.
The signal no longer stays on as long as it used to. It used to give me at least one extra blink, sometimes several. Now it might give one extra blink but more likely stops on time.
Lane changes are much more decisive and better overall.
Tesla started off the same way and told me that they planned to charge for it eventually but still didn't have a firm answer. Eventually, they came up with something concrete and it went from "a sales person told me that maybe..." to "the app said that I have free connectivity until this date, after which..." For those who bought a car in the "a sales person might have mentioned" days, they kept it free for life.
Lucid is still in the "the sales person told me...or told somebody I knew, but I didn't get anything in writing with a cutoff date."
I would hope that Lucid would do something similar for early adopters who bought a car when the company needed it the most and who paid premium prices. They could decide to charge anyway, despite the ambiguity, and if they still allow full functionality with WiFi tethering, a lot of people might be fine with it.
If it could be updated, it wasn't bricked. I don't know where this trend of calling something bricked when it's merely temporarily inoperable came from, but if we refer to that as bricked, it doesn't leave a word for something that's actually bricked. A device, such as a phone, that fails during an update, and leaves it in a state that won't let anybody get to a state that allows an update to be installed is bricked. The device is effectively like a brick in that case because it can't be fixed. Nobody's car was bricked.
"Announced" is pretty vague. In the one situation when it actually mattered, Lucid did make a concerted effort to notify people. It's not the same as merely seeing a message on the phone or in the car. But in general, any ambiguity is on the maker, and that's Lucid. It's reasonable to say that you weren't notified if you didn't see a notification. If you don't normally use an app, you might not see one. Email doesn't always make it through. Things get lost in the mail. And some people leave their cars parked when they are out of town. But Lucid took a multi pronged approach. I wouldn't think that this would be a general problem, and unless they can say that your lack of action caused actual harm, and a repair is the result of the harm from the lack of your action, they aren't going to void any warranty.
I think that people who are worried about losing warranty coverage if they wait too long in general are reading too much into things. Lucid can't say that something failed for reasons unrelated to anything you did or didn't do, but they won't cover it based on what you did or didn't do.
