If I recall, the problem was that the lack of a date-specific
generate_series function would result in a date value being coerced to
timestamp, and thus adding generate_series(date, date, step) would change
behavior of existing code, and that was a POLA violation (among other bad
things).

By adding a different function, there is no prior behavior to worry about.
So we should be safe with the following signatures doing the right thing,
yes?:
generate_finite_series(start timestamp, step interval, num_elements
integer)
generate_finite_series(start date, step integer, num_elements integer)
generate_finite_series(start date, step interval year to month,
num_elements integer)
