I mean it isn't crazy from a flavor standpoint, but it seems frustrating for the player and it seems like just one more task for the DM to track, unless they go out of their way to be annoying about it, in which case it just sounds bad.

As a player, this would make me choose pretty much any not-cleric class. There are plenty of options if I want a full caster after all.
These comments nicely summarize how I'd feel about it.

This could be interesting if done once, and briefly, as part of an ongoing plot, with the understanding that this was a radical departure from how clerics ordinarily operate and wouldn't be the norm.

But as a default house rule…no. Part of the strategy of playing a divine caster is working out what spells you'll need each day. Take that away and you're more of a mindless drone on the spell front.
