Why Are Healers Not Allowed A Gameplay Loop, Anyway?

And a "healing rotation" is pretty pointless if the DPS can avoid taking all telegraphed damage

This argument only works if you're against changing encounters, but based on the fact your solution includes changing encounters; the argument doesn't work.

If changing encounters is on the table then a healer rotation is not pointless and is quite the opposite, because there can be an increase in unavoidable damage to force healing and therefor make the possibility of a rotation. There are comparable examples of other games that use a variety of proc's and synergy between spells to force healers into maintaining a rotation so their core heals are effective. I'm not saying this is a solution, I'm just pointing out that the blanket statement you made is subjective, and in my opinion, wrong.
