Ouch, sorry @konsolebox for the missing feedback. I assume this request just got lost in the mass :(.
In addition to what @elextr said, I think the whole feature could be renamed from "Draw intense colors in bold fonts" to "Allow bold text" which, for me, is easier to understand and is also what other terminal emulators use.
Apart from that, I think this would be fine to merge (still in 2021!!)
