Actually, we are being very careful about this in the deprecation of IPv6 site-local addressing. Christian Huitema and Brian Carpenter have co-authored a very carefully written deprecation document that makes it clear how these addresses should be treated to avoid problems with existing site-local implementations. And, we are planning to instruct IANA not to return these addresses to the regular allocation pool.
