While AIX 7 is the only product certified for V7 today, others have been
certified in the past, but stopped renewing their certifications.

Oracle Solaris 11.4 was the first product to earn UNIX V7 certification:

The blog also incorrectly states the support level of Solaris - only
Solaris 9 and earlier, and Solaris 11.0 through 11.2, are in what
Oracle calls Sustaining Support.  Solaris 10 & 11.3 are in Extended
Support until January 2027, Solaris 11.4 is in Premier Support until
November 2037, and continues to get new features in quarterly support
updates, as I post on the Solaris blog:

As for the blog comments that HP-UX is "genuinely fading", I'm surprised
it doesn't note that HP actually has ended support for it:
