For instance, ktexteditor.git has a multicursor branch, and just getting the "current" text layout is not enough. Could you change it to textLayout(int line), along with a comment that the returned pointer is possibly a nullptr?

I'm trying to expose KateWrappingCursor class, but problem is that it requires access to KateViewInternal which we would still need to expose instead of currentTextLayout(). Any idea how to solve that?
