You mean it can't be a completion-at-point-function?

Indeed the completion-at-point-function don't double as commands the way
company backends do. And while it's easy to create a wrapper for it,
that wrapper will inevitably end up choosing a particular UI, so if we
want to use Company for it, we're stuck with a dependency on Company.

That can be a delicate balance, indeed.

That's true as well. Of course "turn it on" is not always as clear-cut
as it sounds. Adding oneself to company-backend might be seen as "turn
it on", but if you consider that it's only actually used if you do
enable company and if you use the appropriate major mode (or compiler
backend, or snippet library, ...), then you may decide that it's not
really "turned on".
To the extent that ELPA packages are normally installed by the end user
(my install.el package distinguished "system install" from "user
install" but package.el doesn't really provide much support for
system-wide installs, thjo it doesn't actively prevent them), I think
it's not that bad if installing a package also turns it on.
E.g. AUCTeX does just that (with a custom var that lets you "opt out"
if you prefer).
Of course, for people like me who install GNU ELPA via "git clone elpa;
make", we get all packages whether we want them or not, so "turns it on"
shouldn't be too much in your face.
