My biggest concern is that Bitcoin full nodes will become more complex and need to validate against external side-chains too, thus require more data.

As it is, the steady blockchain growth-rate makes full-node storage capacity predictable.

This removes that predictability.

With BMM you dont need to validate it, you just get a hash of the state of the side chain, hence "blind". At least that's how I understood it.

I could have misinterpreted it.

IMHO the success of Bitcoin depends largely on cheap full nodes without additional complexity.

Having extra functionality that only poses risks for opt-in users is no biggie as long as the risk and complexity doesn't spill over to those who choose not to opt in.
