I think it's supposed to mean that they wanted to set the tone as first champions and have the opportunity to put the division/titles on the map with meaningful feuds and some hot matches. Nothing unreasonable or that shouldn't be expected from an inaugural reign in a new division. But instead, because of bad booking and poor planning, you had an initial reign that was cut after just one quick mini-feud and a multi-team match. And now you have the new champions bouncing back between both shows to take pins for no real reason. Things are off to an ugly start.
The issue here is the shitty booking, but for what it's worth BHC weren't two midcarders randomly thrown together. Bayley literally debuted on the main roster as Sasha's tag partner in 2016 and their characters have been linked on-screen and tagging ever since then. They have separate identities as singles competitors, but they definitely weren't a random pairing for the sake of a tag team division (i.e. Naomi/Carmella).
