Yes, you can rely on the presence, but not on its function.  Mail will be 
swallowed in many cases, as I have pointed out, and that is true independently 
of the system.  (I only expect GNU/Linux users to be more savvy about their 
system / Emacs configuration.)

The default is flexible.

Can you point to the code that does that?
`browse-url-browser-function' is initialized (defcustom) and set to 
`browse-url-default-macosx-browser' on a Mac, which is a function that calls 
"open".  That will do the right thing in all relevant cases of a http:// or 
mailto: URLs.

The system keeps track of the user-preferred mail client and web browser.

Could you investigate why that doesn't work for you?

Why is it a hack again?
It relies on accepted and standardized URLs.  I have previously pointed out the 
standard to you.

Brittle, maybe.  But less brittle than most other solutions...
