You're technically correct (the best kind of correct), but in the context of this comment thread the comment I was replying to said:

> many messaging softwares seem to not understand what feature parity is.

That implies either no intent to implement feature parity, or having had enough time & resources to do so without bothering to. Neither of those things are the case here - hence my breakdown.

I've edited my comment to better address your particular point though, thanks.
