@Babyrocko1908, fwiw, I did the same in our mtn vacation home. Here are my reasons:
1. This home is rented for the winter months. The receptacle allows a renter to unplug the CP unit. And use something else.
2. I used existing in wall 6 awg wiring for a kiln that was not long enough for hardwiring, and I did not want to use a pigtail on a high amperage circuit. Replacing the wire to the panel would have required removing finished drywall.
3. Most importantly, do not underestimate the construction of the Hubbell receptacle. Consumers never use/see an industrial device of that quality. The amount of pressure it takes to fully insert a 14-50 plug into a Hubbell is huge. It took me pressing my full palm and leaning into plug to insert it in the Hubbell. And two hands to remove it. I would guess four times the force needed for a Leviton. With a Leviton, I can use two fingers.
4. Redundancy. If the CP wall unit dies, say at midnight, I can simply unplug and whip out the Lucid cord. The home is in a remote area. Gu
5. I don't plan on ever unplugging the CP.
6. The Hubbell receptacle gives off virtually no heat in EV use. After 20 to 80% SOC all night charging, my Fluke temp meter shows almost no temp rise on the face of the receptacle and no temp rise on the plug.
So, I agree that hardwiring is better. My residence has it. I always encourage it. But using a 14-50 receptacle can be done safely if done right, just more variables: industrial receptacle properly installed, and removal/insertion of plug is infrequent.
Hope that helps.
