Note my previous message was an attempt to help in thinking about 
options for your needs.

 From our perspective, I think the intention is to no longer make 
promises about NSPR/MPR APIs remaining available.

Brainstorming again about your needs, maybe it would be more practical 
for you if you took to opposite approach?

You could decide that you keep maintaining the old NSPR libraries, as 
long as you need them, and backport upstream MPR fixes to it, if necessary.

And instead of having a shim from NSPR to MPR, maybe you need it the 
other way round?

Don't use MPR as distributed with NSS, but rather use a shim MPR library 
that maps the new symbol names to the old NSPR symbols?

I think the dilemma here is that the Firefox team would like to be more 
flexible and make changes more easily, which isn't easy to align with 
your needs for long term stability.
