Nice replies.

Honestly, there’s one thought I have.....If we’re at the point that AA has “basic economy” which means one small personal bag and no roll-aboard carryon, then....the implication is that the next higher fare (which would include a roll on and personal item) is charging you to bring on a carryon....So...its not entitlement for OH space but the idea is that the airline is charging for OH space...

That’s just my perspective..
