My ideal lighning wallet would support both Fedimint and LN, but will use mints only for either small amounts or for a short time. If I'm trying to receive a payment that I do not have inbound liquidity for, the wallet would receive it into Fedimint custody, then rent inbound liquidity, wait for the lighning channel opening to settle and then transfer the funds from the Fedimint into the channel. <10 min custody.
My ideal SN would pass Fedimint tips between the users, thus being a custodian only until the receipient logs in and receives their coins. But the present SN works fine, too.
