Yes, I think so. There's already fill-french-nobreak-p, why shouldn't
there be a Polish predicate?

Not necessarily: that space that precedes the word is by itself a
line-breaking opportunity. IOW, Emacs will break before 'a' in " a",
and the penalty will be only 1 character. By contrast, breaking
before the parenthesis in your case will yield a penalty of 2
characters, which is a different tradeoff, worthy of asking the user
explicitly to agree to.
The default value of fill-nobreak-predicate is nil for a reason.
Thanks.
