Sorry, something went wrong.
This constraint was added out of a caution with the thought that nobody uses it. Turns out ora does use it. In practice, this only affects cast to and from datetimes (or possibly strings but that seems even less likely). Tested via ora (see numpygh-21365) the paths are not particularly special, but the parametric dtype resolution is in principle missing. This is not particularly problematic, since NumPy barely exposes that though, and it never worked. Closes numpygh-21365

Test is missing, it could be added a rational to string cast probably, but overall it seems ora is working fine with it (see issue) and I always only added the check because I thought that without a proper dtype resolution, this is probably useless in any case. (proper dtype resolution was not possible previously)
If there is a small chance of another 1.21.x release, this should also be backported to there.
