In the past I've noted a lot of change for the sake of change. Not to say it is the case here, ...

Yes, I don't think it's the case here.
There's good evidence that this change was deemed necessary.

However, I've just built perl-5.33.8 on Windows, without -fwrapv, and all tests passed.
This was using gcc-10.3.0. Maybe Windows was never affected, or maybe something has changed with gcc-10.3.0.
I'll test more extensively with perl-5.33.9 when it comes out (either later today or tomorrow), and add a report to https://github.com/Perl/perl5/issues/13690 if I can't find any need for -fwrapv 
C:\comp-1020\perl-5.33.9\win32>..\perl -I..\lib -V:archname
archname='MSWin32-x64-multi-thread';

C:\comp-1020\perl-5.33.9\win32>..\perl -I..\lib -V:d_nv_preserves_uv
