mostard is a fork of the older version of nostrudel, nostrudel's newest features made it too heavy and bloated while mostard is minimalist, it doesn't have full monero support yet because I need some time to work on it but even replacing LN and ecash for monero reduced the code by like 10x

Non popular opinion I think ecash could live beside monero
maybe, my main LN wallet on nostr is now npub.cash because I gave up trying to run so many nodes, services, web servers, exposing ports, just to get a ln address to receive payments lol so it still exists in other clients but also you still have the usual LN issues when coming in and out of ecash like if someone runs their own LN node and channels, they need good routes with capacity to the mints, etc.
Monero only is a minimalist choice, which is easier for development and creates a unique environment on nostr, anyone can send to anyone, anyone can receive from anyone, and everyone owns their own money, privacy is the default, "with the power to selectively reveal oneself to the world" (cypherpunk manifesto)
Yep I get it but take a look at the new iris.to they have a ecash wallet now and on the initial setup you get a npub.cash address and can start receiving zaps.
For those missing Garnet we have Mostard now.
