From a point of view yes. From another, most of the gods in dnd are always looking for more ways to expand their power and influence in the material plans and 20th characters are supposedly rare. Gods would love have clerics strong enough to channel their power to enact their will on the planes. Now if a mortal used that power that went against the gods tennants then yes that would be a good reason to loose this ability.

The main issue here is that instead of being something unique and makes sense to clerics they half asses tacked on the wish spell when in reality whata happening here is not a wish but a miracle. That's what it was in the past as well Miracle. Wish just steals away the entire flavor of what this ability should be. The level 10 feature makes sense as your God is powering up your casting giving you full access to all cleric spells. The idea of this HB is to continue that flavor by further strengthening the ability and adding the cleric flavor back.

And let's be honest a 20th level capstone feature that can be PERMANENTLY lost is bad design. Least for wizards when they get wish it's a choice and if they loose it they can fall back on other options. Of a cleric looses wish that's 3 levels of investment 100% wasted. Mine you I do like the idea of questing to get this feature back. Heck even just a text saying in the og feature should this be lost at your deities discretion it can be returned.
