We rely on wildcards to register 90% of our applications.  The service
name and description are meaningless.  We only have a handful of
registered services this way and I'm much happier as a result.

It simply would not be manageable here.  URLs change, applications
move, go offline, etc.  Big universities in the US are like
federations unto themselves, and you don't have to be on the Shib list
to know the fundamental difficulties with cooperation between
federated services.  So the crux of the difficulty here is in
management over time.  Wildcard services are simply much more agile.

The issue is not which checkbox but the logout URL.  There is
absolutely no standard for logout URL patterns that could be applied
broadly, and any attempt to encourage standardization would be a
failure before it had even started.  I believe that would be generally
true, but it's certainly true here.
