Sure, the main thing IMO is it has to not sound like or lead to harder internet searches. VST is great because nothing else comes up. CLAP is too common, AUF would be IMO the best not because it sounds cool but because putting in a search engine "Zebra CLAP" will get a lot more weird hits than "Zebra AUF".
Or to put it plainly, VST is gold, probably not going to get another acronym that works like that, AU, AAX are both pretty bad, but we got used to them.
