I have a feeling you're concocting a very far-reaching scenarios and
making a lot of unbased assumptions there to arrive to pre-defined
conclusions. Any programming error can cost a business money, and any
problem can be fitted with scenario when it leads to blowing up whole
world in the flames of global catastrophe, given enough imagination and
wild enough assumptions.
However, I do not see any technical reason - not involving far-reaching
assumptions following from nowhere - that require repeated generation
produce a fatal error. So far all the explanations seem to be to the
tune of "because it's so bad!" but I don't see how it's worse than any
other fault - such as failing to open the file, database returning no
results because of wrong query, etc. We do not produce fatal errors on
all of these cases - in fact, we produce fatal errors only when we know
there's no reasonable way to go on. I still do not see why just
returning empty iterator with suitable warning does not fit the pattern
of all exceptional situations we have in PHP that are handled in a
similar way. For foreach() specifically, for example, you can put there
invalid - non-iterable - value, and it won't be a fatal error. Why
non-iterable value from generator should be a fatal error?

I think it makes sense to treat it exactly like foreach() treats
non-iterable values.
