For what it's worth, I agree.

Even if there was a supportable way to make apt on i386 use some 
gpgv-based signature verification in preference to sqv, if our official 
documentation slightly over-states the requirement, it will make the 
message clearer to the non-experts who need to see this in the 
documentation; similar to the way we make sure to say that skipping a 
release is unsupported, even though a Debian expert can often make it 
work (at their own risk, and perhaps not in the case of trixie).

I've proposed 
https://salsa.debian.org/ddp-team/release-notes/-/merge_requests/261 to 
explicitly call out a semi-modern CPU as being required for i386's 
remaining use-cases.

(which was subsequently merged, and my MR adds to it)
