No.
The same logic would say we should discourage the // operator.
$^V wasn't really useful until it became a version object. When toolchain
finally drops v5.8 support, and we're all dragged kicking and screaming
into using a Perl major version less than 10 years old[1], then $^V is fine
to use. I don't see any point in discouraging it even before it ever
becomes useful.
I do think the docs for $^V and $] could use a major rewrite to more
clearly explain what each is and when/how each can be used. I'm willing to
volunteer to do that or to be a reviewer of someone else's attempt.
