Then the Perl API needs to allow for the GC to move objects. If that
can't happen, the majority of interesting collectors can't be used.

Your finalizer doesn't catch cycles. Did you ever have problems with
it not reclaiming garbage? A collector can still be useful even if it
can't find all garbage. (Conservative collectors can't for example.)
