It seems to be a fairly logical concept that if you change a 1/4 measure to 4/4, then 3 beats should be added to it. Not sure of what the cooks were thinking by not making it that way.
What they were thinking is that it's
more often the case that don't want your music to move around when you change time signatures; you just want the M:B:T grid to shift
around the tracks. I run into that scenario quite often when recording without a click, and then changing the time signature(s) after the fact to match an improvisation and snapping the timeline to the improv.
Also, I'm guessing that you expected/wanted the new beats to be added
after the setup beat, but if that first beat/bar contained 'pickup' notes leading into the first full measure, you'd want new empty beats to be added
before the pickup notes.
What might seem 'logical' in one scenario might not work out so well in another.
