If you've taken the effort to get good profiles for, say, three rolls of

would create one mediocre profile for all three, and would require an
additional step. So it wouldn't improve your quality, and it wouldn't
save time.
Depends on how far each data set is from each other. For example, on my Fuji
PG4500, the differences in Matt versus Glossy paper are quite small (an
average deltaE of well under 3). Using one profile from each averaged data
set allows me to use one profile for either or both. In *some* production
environments, that's useful.
The beauty of MeasureTool is it shows you in various deltaE scales how far
two devices are and you can decide if it's useful to average them into one
profile. Another example is where you have a device (like some presses)
where there is some deviation over the press or run. Again, if it's not far
off, averaging multiple data sets into one profile can be useful.
