I fully agree with you.
The last (ever!) pioneer all in one that I bought 4 or 5 years ago only had microphone input as an option on one of the music faders. So you were down to 3 music inputs if you wanted a mic
Ironically, I think denon consoles (not fair to call them just controllers any more) have very very good quality mix channels as far as naked mic channels go, but then badly implemented “mic extras” get superimposed on top of that pure signal and make it crap out , like over trigger happy gates and could be better ducking and routing
