You can only safely use dtypes that are a single OBJECT array. If a
record data-type has object members, it is not accounted for in all of
the code that special-checks for object arrays. Basically, all of that
code would need to be adjusted to deal with has-object (i.e. void arrays
that have a part of their memory layout that is an object).
The issue is that reference counts need to be handled correctly for that
portion of the data-record. This was not considered as the code was
written, so it would involve a bit of work to get right.
It absolutely could be done, but it's not on my priority list and my
time for working on NumPy has dwindled.
