Reticulum looks very cool. What would need to be changed to support it? How much breakage? Would you be tunnelling IP over it? I don't really know anything about it.
I've done only a little with Reticulum so far. Maybe we should aim to support LXMF rather than plain Reticulum (asynchronous, store-and-forward allows LXMF to work over intermittent networks). Either way we just need to store a key and some way of flagging that its a Reticulum (or LXMF) address. The #meshtastic people might want an option, too, but I know next to nothing about their work.
