On the historical front, wraps & update_wrapper were only designed to handle true wrapper functions (i.e. those that don't change the calling signature).

For anything else (including partial), I considered it unlikely that the doc string would still be accurate, let alone any of the other metadata, so I didn't worry about supporting them.

That sais, if it's practical to make the results of combining the two less broken then I agree it would make sense to do so.
