The point of introducing level 3 - a stripped down version of level 2 -
was to transition clients to using it and then discard level 2, instead
of having to find everyone using annotations and work out whether we
broke them every time someone wants to strip something out of level 2.
When everyone we care about is happy with level 3, we can kill level 2.
Bob, sometimes I feel like you pick very strange things to label as
"hard". What's hard about autodetecting the availability of annotate
level 3? Or even doing it based on version number?

Annotations are going to go away. Period. Not yet - not until we
agree that MI is ready - but I expect level 2 to go away before level
3.
