Isn't it inconvenient and search result partitioning to use this? I haven't come across/noticed it before. In English for example we use the French order acronym UTC, not UCT or CUT. (Though to be fair in the UK outside of a computing context we mostly use GMT.)
It's my understanding that we use UTC because it favours neither the english nor the french. English wanted CUT, french wanted TUC, so UTC was chosen to favour neither.
I generally prefer when we agree on a spelling, even if it isn't in English. CERN is a good example of this, no English speaker in their right mind would call it ECNR.
