Casting Mordy's Private Sanctum everyday for a year causes it to become permanent, are there any DMs out there that apply this same cause/effect for other spells as well?

I find myself playing with the idea of casting spells, whether high or low level, repeatedly on the same spot/object should leave their effect permanently (especially if cast for a year) but am curious as to what the DMs out there think of this. Be creative, place limitations, unless you want perma Meteor Storms lol 

Druid Grove is similar, but doesn't become permanent.

 If you cast this spell in the same area every day for a year, the spell lasts until dispelled.
