Polish Kreska in UC

I see acutecomb, but not acutecomb.case + locl.

Is there a kreska in UC as well?
From the references I find online, it seems to affects only LC.

The localization tutorial is ambiguous in this regard.

To answer my own question: there is a sentence by Twardoch from his reference guide:

“Kreska over capital letters may run flatter, thus looking more similarily to the acute accent, especially in text typefaces.”
