Yes, the commandline python gives some reassurance that you will have a way to access the wallet, but I do not trust third-party solutions I have seen many companies simply close their doors and the clients run out of support
It's a good thing Trezor (and the python software) is fully open-source, so if the 3rd party option (Satoshilabs) goes under, we still have the source code for both the device and the software, and can thus recover our coins.
(Sorry for replying so late, I hadn't noticed your comment earlier.)
Good point if the developer community it is strong enough to support the software and update it gives something more confidence, to be able to change the solution If necessary
lol np
