That's my interpretation as well.  But it's mentioned multiple times
on this list that you can assume that Lua GC is non-moving, so I
expect that programmers have come to rely on this.

The implementation permission might be useful for a collector which
performs emergency compaction to reduce fragmentation, similar to
Hotspot's CMS collector.
