Eh. Strongly consider not porting deprecated things. :) PropertyAccessor could even be deleted for the next release, Twisted 13.1 (this would be a relatively quick deprecation/removal cycle, but it just fits within the defined policy), if it is a maintenance burden - and forcing us to solve the metaclass issue sounds like a bit of a burden.
