I'm gearing up to write some Robot Blasphemy

So I got to thinking -- it could be interesting if some of the negative bias towards flight frames we see comes from them having an implicit association with space and the orbit, which is directly opposing the planet (Primus) and is thus associated with Unicron.

Like, nobody ever really thinks about it, but maybe Unicron gets portrayed as having a aerial mode or at least suggesting one (and he's definitely portrayed as having a root mode reminiscent of Predacons, so there's that). We have a soft confirmation that Megatronus -- the closest Lucifer figure they have -- had a flying alt mode, since he was who Megatron was modeled after when he became a gladiator.

There's probably canon (including in-universe canon, because it is a religious matter, after all) over what the alt forms of the Thirteen were, although there's also probably plenty of debate which one of them even had alt forms, and plenty of debate over whether transformation originates from Primus or from Amalgamous Prime.

Hell, fringe opinions doubting the divinity of the Thirteen probably exist, too, if it's not even a settled matter over whether Cybertron is Primus or simply his creation.
