Nope, and it isn't necessarily introducing an incompatibility either. It
is a conscious decision the actively support recent-ish Perl. It does
not imply SA not running on 5.6 (maybe with some customization).
It does however mean that we will not have to work around any Perl 5.6
issues during the entire SA 3.3 lifetime. Keeping compatibility is a
nice bonus if feasible, but we are not guaranteeing it.

See bug 5574. Even 2 years ago we where "having a hard time supporting"
5.6 (as you put it so nicely ;), because there was no infrastructure to
test compatibility on the devs end.
Even worse, that very bug shows that critical fixes might need to be
back-ported. That means smoke-testing on ancient Perl 5.6 up to the end
of the 3.4(!) lifetime.

Also, keep the nasty hacks in mind (bug 6131), which effectively means
we are incompatible with the latest Perl, for the sake of Perl 5.6
compatibility. That's a bad trade-off.
