Sure? it would be hard to acquire.

I am not very comfortable with having a privilege account.
Actually I recently reconsider bringing back the inherent version of the migration (the main issue was the code was a bit everywhere and less cleanly separated, but looking backward, it would have really feel more comfortable to me).

type SignedFilter = frame_support::traits::NeverEnsureOrigin<AccountId>;

// Use same weights as substrate ones.

Would be more appropriate to benchmark it properly in this runtime.

yes, not sure how much change it will be to do so (in theory there is no reason to see significant change: only wasm bin size may interfere a tiny bit maybe).

Your comment:

It may be pertinent to avoid adding this in a runtime upgrade that already have others migration.

would be suited here so whoever does the move from Unreleased to VNext is aware of it.
We can then drop the comment.

You need to add it to the list of migrations.

Some comment about how this number is chosen would be good.
