IPv6 requires renumbering when an address that has been used is no longer
appropriate (which will generally be because of changed topology, which
may be local topology changes - moving a host to a different LAN, or
global ones - connecting to a different provider).   That is the only
reason. As long as prefixes remain usable, they can keep on being used,
with other prefixes added as required.

Well.. all you need to do to fix this is to make a rule that if a
global prefix becomes available, the site-local prefix is no longer
appropriate and must be withdrawn.

this only solves one of several problems with site-locals, and it removes one
of the few supposed benefits of site-locals - that such addresses will be
stable across prefix changes.
