There should be no downside in allowing any kind of origin for remark.

So in theory this is fine, but in practice this can be used to inflate indexers / archive nodes.

Sorry, dumb question: Why does this not allow unsigned? Do we not allow unsigned by default?

Who would then pay the TX fee?
I think to support unsigned tx, the pallet needs a dedicated validate_unsigned hook to manually do the spam protection.

Unsigned transactions are rejected by default. As @ggwpez said you need a proper validate_unsigned to accept them.
