The chief difficulty I see is that in some modes, indentation isn't
idempotent: if you ran indent-line-function from some generic electric
code, it might change the indentation of the current line in unwanted
ways. (Imagine python-mode, where indent-line-function cycles through
feasible indentation levels for a given line.)
At best, modes would have to opt-in, and if each mode needs some glue
anyway, why not just let each mode handle electric characters itself?

Thanks.

There's no particular reason, no. The cc-mode set of electric characters
is probably fine.
