My reading of the original comment was that a distinction was being
drawn between "svn add" and "svn commit". If the client dependant
property setting was only happening on "add" (and "import") then it is
ok if it is not perfect (same as current binaryness detection). If it
is happening upon "commit" then... er, that is not going to work unless
it can read my mind perfectly.

Given that the setting is happening upon 'add', I would expect that
'add' is going to print out the auto-set mime-types. If any are
incorrect, you could correct them before the first commit.

Forget performance hit, the server simply doesn't have all the
information the client has. What type is the following file from my
repository: "Robot-Learning"? My local file system knows that this is
a powerpoint file. Sure, you might use a magic-number approach to get
this 80% right on the server, but the client already has the
information.
