It's not that easy to enable mod_php globally except for one subdir, at 
least for the casual admin. For the FilesMatch, one would need some 
advanced regexp foo. The same is true if you have AddType'd various script 
extensions.

The example config at 
http://httpd.apache.org/docs/2.2/mod/mod_dav.html#complex recommends using 
'ForceType text/plain' to override the 'AddType application/x-httpd-php 
.php' that most users have somewhere else in their config. This is a 
pretty bad hack, IMHO. Most files in the dav directory will be delivered 
with the wrong content type.

mod_dav is not treated differently, is should just handle the request. The 
fact that it delegates this to the default handler for some providers 
should not concern the average user. Or how do you explain to a user that 
a config that works fine with 'Dav svn' does not work with 'Dav on'? (Or 
the other way round, depending on what you are trying to achieve.)
