What if the generator is passed in as an argument

Secondly, it would be nice to automatically revive it.
For example, when another for-statement or other
equivalent is applied to it.

That last point would definitely be incompatible. It's quite useful to
be able to peel some values off a generator, then use a for loop to get
the remainder. Simplest example I can think of would be to read a file
where the first line(s) represent header information, and the body is
obtainable with a simple loop. I wouldn't be surprised if the csv
module does that.
Not arguing whether an explicit revival is useful or not. Although as
others have pointed out, not all generators could accomplish it, and in
some cases not unambiguously.
