Unnecessary parameter?

Yes, I have thought of it many times, but with my template-writing skills it is less cumbersome to continue writing the cases out. Also, it is sometimes useful to have the free-text option for some noun and pronoun forms which are not considered cases, such as prolative form of maa:

^{The template Template:fi-form of does not use the parameter(s): n=pl}

of maa (by land, over land).

Forgot to mention that the prolative of maa is maitse.

I withdraw the comment on free text. It is probably more practical to classify maitse as adverb. One might mention the prolative-ness in the etymology section.
