There are a number of PR's that require breaking the
library's ABI.  We've always punted the decision down the
road, but at some point the ABI is going to get broken.
I thought that a meta-bug report tracked the ABI breakage
PR's.  A quick scan of bugzilla titles did not have one
jump out at me.

Personally, I think we should bump the library's major
version number and start to introduce the long delayed
PR's.

Of course, I have little to no time to actuall fix
anything. :)
