The proposal is to make it not work.

I doubt that many people are aware of that, and that even fewer of them
understand what that means.
Anyway, the string 'use UNIVERAL;' appears in 74 dists on the CPAN
according to grep.cpan.me. At least some of them are completely
redundant in that the file that includes it doesn't also include a call
to UNIVERSAL::isa or its friends (presumably it used to in an earlier
version and the 'use' hasn't been deleted), but not all are.
