Sounds great in theory.
What we see in reality is that append-only database is unusable without making additional "projections" or whatever you call them, databases that are ready to be queried/updated, with maybe specific denormalizations, indexes and so on.
And oh, btw, those later databases are not "imutable".

I highly recommend the talk “Domain modeling and with Datalog”[1]. It gives an explanation of how all this works, including indexing. 1: https://youtu.be/oo-7mN9WXTw https://youtu.be/oo-7mN9WXTw
