In this post I list 22 steps on how to SAFELY receive your BTX from a Trezor. The steps for a Ledger would be mostly the same, except for step 6 (erase your Trezor). To erase your Ledger, simply enter a wrong PIN number 3 times.
Besides that, simply replace the word "Trezor" with "Ledger".
This is too careless IMO, asking people to compromise their Trezor seed and erase their Trezor.
Trezor is also used as a password manager and for U2F logins, not just for storing coins.
It is also not practical for people who have part of their seed or their entire seed words stored with lawyers or relatives or as part of their will, possibly with a lot of care to bury or otherwise hide it, maybe even in different physical locations throughout the world that might require travelling.
You don't just change a seed like that, especially people with significant holdings or who do hold all other kinds of coins in multiple accounts, have set up multisig accounts etc ...
