I've tried to stay away from the "web tech on the desktop" trend. network-connected/cloud apps are great, but the current web tech does nothing to solve it.

Things like atom inherit js etc. which gains a little bit of speed up and familiarity, but also performance overheads and complexity.

Not actually good, js-devs are the worst for a kind of NIH and low cross-pollination. Sometimes, a string custom and/or C-API is the nest for bringing in multiple communities.
