Comment (by g1smd):

 Avoiding the two slow and inefficient disk reads (for requests that are
 generally not going to be rewritten) sees a measurable increase in server
 efficiency.

 Although there may be "110 file types", applying this thinking purely to
 the requests for images already sees improved handling for 90% or more of
 non-HTML server requests.

 Mod_rewrite offers a lot of powerful features, written to be highly
 efficient, but most Open Source developers ignore all of this and simply
 code

 # and the requested path and file doesn't directly match a physical file
 RewriteCond %{REQUEST_FILENAME} !-f
 # and the requested path doesn't directly match a physical folder
 RewriteCond %{REQUEST_FILENAME} !-d
 # internally rewrite the request to the index.php script
 RewriteRule .* index.php [L]

 which is the absolutely worst way of doing it.

 With this method you then have to write PHP code to "understand" what
 "type of" request was made and call the right module to deal with that
 request.

 This functionality could have been far more efficiently coded using a
 compact RegEx and rewrite function in .htaccess. However, this can only be
 done of there is a cohesive plan for how the URL space used by a site is
 divided up: and therefore a simple way for different types of content to
 each specifically match a single RegEx.

 It seems that database coding comes first, and "how this impacts the URL
 space of the site" comes last, if indeed it is even addressed at all.
