By sidelined I meant not on AEW tv

"Sidelined" in the context you were orignally using it in (" I don’t understand TK.") is blaming TK for something within his control, for booking choices. "Not being on AEW tv" is a bad metric to define it by as there can be countless reasons for someone to not be on AEW tv outside of "TK doesn't wanna book them". There's been women stuck out of country, injured, pregnant, filming tv shows, prior commitments, and none of those TK has any control over. There's a few women who can qualify as being "sidelined" for various reasons, a bunch of the women you have named so far just plainly do not fit that category, et al (although fairly, some that you named do, just not all of em).

so my perspective may be incomplete.

It is. ROH may be (at this time, unfortunately) pay tv but it does not exist in a non-canon bubble. What happens on ROH is canon to AEW and vice versa, regardless of if you have to use an app to watch it instead of changing a channel on a television. Hell we've had Death Riders matches the last few weeks with wheeler and marina on ROH lol
