easier to warm up than cool down imo

Clothes-wise sure, we put it 100W at rest, we need only capture that.

I really don't get why you can still buy cooling-only air conditioners when any heat pump can work just as well in either direction

Every aircon should heat or cool the indoor space as required

Then it becomes easy to cool or warm at ~400% efficiency

As s far as window units go, one of the biggest losses is in insulation around the window.

Those that have window units do so because there's really no alternative.

Would bi-directional window-mount ACs be effective heaters, given how much loss a window unit sees through drafts?

If it works for cooling there's no reason it wouldn't work for heating. If they need to stand in the air path for cooling they will need to stand in the air path for heat

Yeah but the ∆T between cooling and heating is way different.

Here in MA, we cool as much as Outdoor - 30F, but we often heat Outdoor + 50F. Sometimes more. Drafts introduced by a poor seal (which is often the case with window units) would be a big deal, no?
