Exactly. That's the problem. That's why I only spend time with core lightning. We need more than 4 developers. 

and we need to spend more time reading and reviewing stuff like this (https://reyify.com/blog/adaptors-generalised/)  instead of this stupid top layer app stuff, which is what seems to grab people's attention. 

But perhaps, that is asking too much brain power from folks.

Any examples? 

 i dunno but i've spent a lot of time tinkering with source routing and solving issues with that are central to lightning as well i think, because it's fundamental architecture is (and has to be) source routed 

 Wallets, probably.
