that's correct

I still think specialized clients (i.e. wallets) will be useful and necessary

i.e. I won't bake in a full fledge wallet into Olas, within Olas all I want is for people to be able to signup and be able to send and receive zaps; no need to provide fine grained control, payment functionality to go buy a coffee and stuff like that.

but yeah, it's up to each client to decide how much they build out
