We do have a couple of buildfarm animals on AIX 7.1, but nothing older.
The other systems you mention are surely dead and buried.
Interestingly, although cpan's table says AIX 7.1 shipped with perl
5.10.1, what's actually on those buildfarm animals is
tgl@gcc111:[/home/tgl]which perl
/usr/bin/perl
tgl@gcc111:[/home/tgl]ls -l /usr/bin/perl
lrwxrwxrwx 1 root system 29 Nov 09 2020 /usr/bin/perl -> /usr/opt/perl5/bin/perl5.28.1
Hard to tell if that is a local update or official IBM distribution.

So 6.1 will be five years out of support by the time we release PG 15.
I'm inclined to just update the docs to say we don't support anything
older than 7.1.
