Now have tools to see all plans, etc...
See plan cache commands.
Ability to get the list of remembered query plans from the server
Support admin hints per query pattern
Add query plan history and logging
clean/fix exception handling in query plan runners
Add logging to indicate when cached query plan changes
All the information is available via other methods (profiling, verboseQueryLogging, query plan cache commands). We don't know if we want to log into a special collection yet.
I think what we've done qualifies, didn't need to do the original description.
Will fix and resolve.
