I don't see a need for an option at all.  All tree-sitter based modes
use these search functions, so treesit.el simply acts on their behalf
here.  It makes no sense to let users control how a major mode
customizes outline-minor-mode, because the major mode is supposed to
know how to adapt outlines with its main syntax, and what a heading
means in the context of that mode.
