Try:
add_methods => [ 'count' ],

I'm trying to balance default functionality and keeping the namespace clean.
IME, names that begin with count_ are somewhat common as column names, so
the count method is not in the default list to avoid relationship count
methods from conflicting with column methods.

That'd work fine, or you can override some methods in your custom metadata
class and add the count method type to your relationships before the class
is initialized.
