Is S/be commonly known ?

@PeterJudge-PSC Is S/be a common abbreviation, should I add it to the TL/DR AFAIK IMHO list ?

First time I saw S/be :)

I'm not sure how common it is, but I like it for subject lines. In case you care, I have a few others too ...
s/be = should be
s/not = should not
w/ = with
w/o = without

Thank you for the list, I don't mind learning some new abbreviations.
