Having a get_history shouldn't preclude getting such history from a
prefix filter like the ones proposed in the new api.

Otherwise, I think like Amir, we would do a quick get_history (possibly
with prefix) and then we would spv taking a bit more time and ideally
showing some feedback about the validation status of each tx.

Thx for pointing this out Amir.

cheers!
