skipna is not passed as a kwarg, now it is valid keyword for astype
Right I'm not sure - would you delete this argument and have skipna=True in astype_nansafe? Then it would be API breaking change  @t0ma-sz i don't think its worth restoring this at all, rather fixing #25353 would be useful. closing as wont fix - the underlying cause should be addressed rather than adding back unsupported api
