the recipient is EXPLICITLY saying "zap me on these mints" -- so this point is kinda moot
right now the vast majority of nostr users are on either alby, WoS or primal (myself included)
with this, instead of having a couple of huge custodians you can disintermediate that market and have and use, at the same time, 5, 10 custodians
you can and should sweep the balances from the WoS of the world into whatever you have.
There are many people running small LN nodes that are not being used as their zapper because running a zap-capable LN nodes is much more involved than running just an LN node.
With this you could literally just use the custodians while you are offline and the moment you come online sweep everything to your own LN node.

it wasn't clear from the demo, so it assumes that the people sending the ecash "zaps" are using the same set of mints? I'm not familiar enough with how cashu mints work for how this would work.
i think it would be fine in that case. as long as the client isn't accepting random ecash from random mints I can see this being useful.
having ecash stored in nostr is a bit sketch considering how people treat their nsec security, but its definitely cypherpunk af to have cash data that you can send around that lives in nostr itself.
How is coordinating the same set of mints achieved?

Why is this still a case 2 years later?
it entirely depends on your expertise level. I made it as easy as possible by providing https://sendsats.lol and by writing a zapper script that you can run next to your CLN node, but people don't even run a lightning node to begin with.
