Spark as an extra trust layer compared to a custodial lightning service
I'm talking re:
where SN began with a custodial wallet
SN already wraps invoices and takes a percentage of payments, it's still a custodial intermediary (CC's never made sense to avoid the appearance of being custodial, but I digress...)
So Spark can't get us back to the original SN state, its no different than any other custodial wallet on top of the original trust in SN.
Nor do I see it as extra fragility
There's all the inherent Lightning fragility, plus the fake L2 swap fragility on top of that, which is also where the fees come from. Again, relative to SN internalizing.
A 3rd party SQL wallet vs. fake L2 you could argue is the same on the fragility side in theory, but not in practice. Abstracting a database over Bitcoin is inherently more complex than just using a database.
