The format for 'props' was never specified and the list for 'errors' is impossible to keep updated when considering that many errors come from MediaWiki backend code and extension hook functions. And since there doesn't seem to be any real use case for either of these, let's just kill both of them instead of wasting effort on trying to fix them. Note that neither getResultProperties nor getPossibleErrors are called from any extensions in gerrit, and none of the other deprecated methods are called outside of the implementations of those two methods. Removing the obsolete methods is left to the maintainers of the extensions, as keeping them hurts nothing and is needed to maintain compatibility with earlier versions of MediaWiki.
