I've certainly have had ports fail, but software is worse, and bluetooth is a lot of software. My spouse's phone was able to connect to our van for some time, then a phone software update broke it, and it took 3 months for them to push a new one that fixed it. If it was a wired 4-pin connection for handsfree audio and either port failed, it would probably take less time to get it fixed. (Yes, a 4-pin connection probably leaves out features from Bluetooth, but no agency to fix problems is worse)

I've yet to have a SIM fail on me, and I don't see why I would want to lose out on the convenience of removing the SIM from old phone, and inserting it into the new one. Moving an eSIM requires interaction with the carrier as I understand it.
