It's basically this on GNU/Linux:

(gui-get-selection 'CLIPBOARD 'TARGETS)
=>
[TIMESTAMP TARGETS MULTIPLE SAVE_TARGETS text/html text/_moz_htmlinfo 
text/_moz_htmlcontext image/png image/jpeg image/bmp image/x-bmp image/x-MS-bmp 
image/x-icon image/x-ico image/x-win-bitmap image/vnd\.microsoft\.icon 
application/ico image/ico image/icon text/ico image/tiff]

This lists the available media types.

I've just had a quick peek at what happens in Macos, and it's very
different there.

(gui-get-selection 'CLIPBOARD 'TARGETS)
=> "http"

So gui-get-selection (or rather, ns-get-selection) has to grow support
for this?  I know absolutely nothing about the internals of the
clipboard on Macos, so I've added Alan to the CCs -- perhaps he has some
insights here.  It basically just calls:

static Lisp_Object
ns_get_foreign_selection (Lisp_Object symbol, Lisp_Object target)
{
  id pb;
  pb = ns_symbol_to_pb (symbol);
  return pb != nil ? ns_string_from_pasteboard (pb) : Qnil;
}

Which seems geared towards text/plain only?

I haven't looked at Windows, but I'm guessing it has to grow a similar
set of capabilities.

Yes, but it would just be too surprising in an Emacs context, in my
opinion.  Changing how something as fundamental as `C-y' works here
would potentially be extremely annoying.
