Taking a new look at the code now, I even see that extra is initialized in a
similar way (at the beginning of _make_safearray_type) to what I did in
create:
if cls._vartype_ == VT_RECORD and extra is None and len(value) >
0 and hasattr(value[0], '_recordinfo_'):
import comtypes.typeinfo
extra =
comtypes.typeinfo.GetRecordInfoFromGuids(*value[0]._recordinfo_)
the only difference there is that you did try/else and I used hasattr.

That could be another solution, to remove the 'extra' parameter from create
(though I don't know whether someone may already be using it and this could
break that code). Another one could be renaming the 'extra' parameter in
create, and assign the bound 'extra' variable if None is provided as an
argument (or filled in by the default value).
