I'd say Ledger is already the most "idiot proof" hardware wallet we have right now, with Trezor coming in at a close second. Instead of working to make updating a bit more easier, they should probably just focus on removing unnecessary bloat on the Ledger Live software because it's slowly but surely getting slower and clunkier as time goes.
I would partially agree with you but Trezor is very much different from ledger hardware wallet.
You can install Bitcoin only firmware in Trezor so you won't even notice most of the update noise coming out, and you can't do the same thing with ledger.
I can count Bitcoin-only hardware wallets on my hand, Trezor, BitBox02 and Keystone can do this optionally, than there is Passport, ColdCard, and that's about it.
Worthy mention DIY bitcoin only signing devices are SeedSigner (based on RaspberryPi) and Krux (based on ESP32 devices).
