I've put a wiki page with a summary of this discussion here:

Hopefully I've captured most of the important points, please let me know
if there's anything I missed, or misrepresented.  I'll add a ticket

Given the new evidence that it's actually rather hard to demonstrate any
performance loss in the absence of the M-R with GHC, I'm attracted to
the option of removing it in favour of a warning.
