all the other major browsers ship on OSX (and many on Linux, etc), where

Right... the GM component (synth) is available, just not the SMF component
(file player). (Just want to be clear about that.)
So if I was in a problem-solving mode, I'd be looking for some way to get
the SMF file-player code into browsers, if not into OSX and Linux
distributions themselves.

The GM (synth) component doesn't seem to be available in an easy
programmable form (e.g. as a MIDI device) on OSX (or Android, for that
Obviously, if we have the right MIDI API, a Javascript synth could install
itself in a background process and create a virtual instrument.  I don't
think I've seen any JS-implemented GM synths yet...  :) 

I don't know what an "easy programmable form" is, as I am not a
programmer... but my understanding is that on OSX the DLSsynth is available
to any Audio Unit Host, so I guess the browser "just" has to be an Audio
Unit Host... whether that is "easy" or not I don't know.
If everyone here understands what synths and SMF file players exist on what
platforms and how to access them, and believes there is little value in
leveraging what is there, then I can accept that. 
I'm just trying to make sure we all know what already exists.
