Polish noun templates - tantum parameter

Would it be a lot of work to add a parameter called tantum to the existing Polish noun templates, taking s or p as its value, so that e.g. {{pl-decl-noun-ja|korupc|tantum=s}} would work just like {{pl-decl-noun-sing|korupcja|korupcji|korupcji|korupcję|korupcją|korupcji|korupcjo}}?

This would reduce the amount of work needed to add singular-only and plural-only words.

I had the same idea for the longest time (except I named the argument |num=)… but I never really got around to implement it.

Anyway, it works now for {{pl-decl-noun-ja}}. If someone moves the rest of the specialised declension patterns into Module:pl-noun (and switches templates to use that module), they shall start supporting it too.

Seems to work, with the exception that [[category:Polish singularia tantum]] is not added.

Fixed.

Regarding conversions: {{pl-decl-noun-nie}} should not be converted just yet. I need to check whether there are any remaining users of |num= first.
