I seem to remember some years ago there was discussion of banning all Latin in official publications as it was elitist.   The R4 Today programme brought in an academic to put the anti side of the argument and he pointed out that, one way or another, about seventy percent of English words are derived from Latin.  The idea died after that and I hope it does again.

What is the difference between a Latin abbreviation and some obscure English ones, everyone uses them whether they know they are Latin or not.  They are part of the every day usage.
