I think that is an accurate assessment! It's actually the reason I prefer it. I only wanted the ability to expand to treesitter text objects and then contract that selection if desired. I almost wrote it myself but then found that plug-in.
Apparently this was changed only recently. I am surprised not many people know/talk about this change. Still looking for a fix.
Edit: I do agree it is annoying but for unknown codebases it helped me a lot.
