I understand your point of view.
However, try this: tie all the steps of a drum track. Also tie the last step to the first one (infinite length note). Select another track. Now, how would you differentiate this track from a muted one as it always stays lit? Even if you do not create an infinite length note, when a note is tied, it is difficult to fastly tell (visually) if it is muted or not. The "key press work around" is way faster.
Hope this help.
Best,
Y.
