Ah I see it now. B and I can be used now for almost anything except ’emphasis’ which is the purpose of STRONG and EM.
If that’s the case, wouldn’t be better if we drop STRONG and EM then? I mean, it’s not like there’s any presentational difference between B and STRONG; I and EM. Unlike when compared to INS and DEL.
Unless W3C plans on imposing a presentational difference for B and I similar to INS and DEL.
