OK, you mean uncomment-region will uncomment this,
while M-; will comment it additionally?

;; code
code

Then, one has to wonder why the second line is included
in the region to begin with? I guess, if you use this
on big chunks of code with comments and code
interleaved, it might be useful.

Yes, but from the users' perspective they know what
state gives what behaviour, so it is just an
alternative way (a better, often) to tell the computer
what to do. Or not having to do anything to still tell
the computer that, if the state is already ripe for
executing the command with a certain behaviour in
mind. And if the DWIM command is good, that should
happen more often than not.
