Conspiracy theory time:
Glameow will be available in SwSh because it's model got updated in gen 7, making it more in line with official artwork. I feel it'd be a little weird for GameFreak to update its model and then not use it in the next games considering Dexit and all that.
I outlined this in a post in one of the SwSh threads, but I also think Heatmor will make it to Galar. It got an exclusive move, Fire Lash, in gen 7. I don't think GameFreak would bother to give a pretty unknown 'mon a fancy new exclusive move if they didn't have plans for it.
