Do you really need to check it, if the seed words are stamped in a steely thing and the thing is sitting in the same location ever since? Be honest.
Discussion
When you set the wallet up did you test recovering into another device/wallet?
What about if you're using a passphrase? Is that stamped into steel? Is it where you think it is?
Using multisig? Are your configuration file(s) secure? Are they digital? Have you checked they still work?
Lots of levels to this. Each one specific to your setup.
There is no reason to check your setup over and over again IF you have set up a wallet or quorum and everything worked, was backed up, the backup was tested and nothing got lost on the way.
But yeah, in general I totally agree with your initial note and want to thank you for all your educational content you have produced and keep up to date. 💜
