Exactly, users discovered dav/davs worked all right so they used them, 
not bothering on the why they where used in the first place (an example 
that probably count as regression [1]).

agreed, more confusion that's sure.

IMHO adding the scheme vnd.sun.star.webdavs whould be good, in the end 
having the pair vnd.sun.star.webdav/vnd.sun.star.webdavs reserved for 
local interaction (e.g. browser =-> LO) activating the UCP WebDAV 
protocol over http/https.

In this way it will be the same for all the platform.
