I use my MacOSX system pretty much exclusively as an X11 server, so maybe
I don't understand enough of Mac OS X's GUI philosophy, but I believe that
the behavior by default for URL should be the same as for Text, except maybe
when the browse-url function is configured to use one of the Emacs based
webbrowsers (like W3, or emacs-w3m).
The idea is that if I want to open a URL in Safari or Firefox, I'll
drag&drop it there, whereas if I drop it onto Emacs I most likely *don't*
intend it to go to my external browser.
Of course, if I have url-handlers-mode enabled, maybe I intend URL-drops to
call find-file as well ;-)

Under which circumstances can X and/or Y be negative?

Please use dolist instead of mapcar here.

Why not (browse-url (cdr name)) ?

What is the rationale for the (image-file-name-regexp) exception?

Why are raise-frame and recenter necessary?

Please factor out the commonality between the two functions into an
auxiliary function.

Does this work? Shouldn't it be [(shift drag-n-drop)]?

be either to change the code, or to add a comment answering
the question.
