pagegenerators.RepeatingGenerator is not a suitable re-implementation of the compat's "repeat" parameters.

In compat the generator runs through all items and repeat that generator again and again with new changes first but it also yielded old items which won't to have again.

The new implementation retrieves the lastmost entry, waits for a time and continues with re-reading starting at the last item found. That is what eventstreams do and it is more suitable to use eventstreams instead.

Therefore I propose to deprecate RepeatingGenerator which btw. isn't used anywhere in the current framework..
