I think removal is not happening.  The documentation for attndims
already says

    Number of dimensions, if the column is an array type; otherwise
    0. (Presently, the number of dimensions of an array is not
    enforced, so any nonzero value effectively means “it's an array”.)

and as far as I know that is completely correct.  (Hence, your gripe
is not that it's not "accurate", rather that it's not "precise".)

There isn't a comparable disclaimer under typndims, but there probably
should be.
