Intentional. The purpose of the grouping is to color the signals
differently.
The colors are nice, but of limited utility. It seems like the
functionality to turn off colors without having to assign them to different
groups should exist. I have no idea how difficult that would be to
implement. My problem is that I have gnd/pwr planes that cover up traces
and would just like to "make those planes invisible" easily at times.

What I do is re-group them as individual layers, do my editing, then group
them back.
Isn't this possibly a little dangerous? You would REALLY need to pay strict
attention to whether lines clear polys (or not) since you wouldn't get the
"feedback immediately" as you're laying the trace. You'd only find out
after you merged wether you left that off for your trace or not. Those
pesky orange-highlighted pads sometimes aren't too instructive of where you
connected two wrong nets.

Yes, maybe. What makes it a 4 layer board in reality is telling the fab "I
want a four layer board, here's the gerbers" :-)
True! but pedantic. ;-)
You can do whatever you want as long as you re-group them as two groups
before exporting it to gerber. The exporters assume one physical layer per
group.
