Can we really get away with changing the return type? That would
by no stretch of the imagination be free; one could expect breakage
of a few user views, for example.
Independently of that, I'm pretty much -1 on going further than PB.
Even if the additional abbreviations you mention are actually recognized
standards, I think not that many people are familiar with them, and such
input is way more likely to be a typo than intended data.
