UA string in requests for metadata?

[Chad La Joie]

In addition it doesn't give you any definitive data.  There are
already organizations that fetch metadata once and then host a local
copy that their entities use.  Other places have test "oracles"
available that aggregate data from many sources and just answer
per-entity queries, all of which is done outside the purview of any
existing federation.  Nascent inter-federation work also routes a lot
of requests away from any given federation's metadata.  Not to mention
the simpler issue that people just don't update their software that
often.

If an entity registrar needs to know the version number of the
software its registrants are running then the registrar would be much
better off setting up a process to explicitly deal with that need
instead of trying to shoe-horn the information in to an unrelated
process.
