Title: Annotation processors should always report the latest version...

as this compat mechanism was ill-conceived and impossible to use reliably in a forward-compatible manner.

It is better to risk (the very unlikely possibility of) something not working right in the far-flung future than to have to fix the supported version every time a JDK is released (thereby breaking compatibility with previous JDKs at the same time).
