Yes, it is mainly the sync feature which uses this request but it's a very important and
often used feature. With synchronizing a file "a.html" I mean to perform a PROPFIND request
on "a.html" in order to figure out if it has been changed after the last time you have
downloaded that file to your local machine. Synchronizing a huge folder means to check this
out for the folder and all its content. So if the user wants to synchronize a folder with a
lot of resources in it it is very efficient to do that with one PROPFIND-infinity request.

Yes, I know and believe that!

Yes, I know and understand your point of view but, as I already pointed out,  we like those
requests because they are pretty efficient for us and we are very sensitive to changes of
the protocol or its most important implementations.
