There has been a bit of talk about adding F3evo support since it did away with the CP2102 chip and uses the F3's native USB allowing the bootloader to work. And the emax femto being based on it is tempting. But...again there's a lot of goofiness with the clones and the developers are focused on the pico blx and polishing up seppuku support right now so another new target isn't likely anytime soon. I've toyed with the idea of trying to make a target for F3evo myself...but...that's a bigger project than I've taken on before and I'm a little short on time right now. My old flyingF4 used custom sensors - which required modifying the default FlyingF4 target...but was really just changing a half dozen lines in the target definition to tell it to use different sensor code - all of the wiring was the same and the sensor drivers were already there. F3evo support would big a bigger project since the wiring is different so I'd have to learn how the F3evo is wired (probably by looking at the betaflight source) and then modify a similar dronin target. I could probably pull it off...but I don't have an F3evo or femto board and don't have funds to get one anytime soon and even if I did have such a big pile of projects already half completed I really don't need another.
Though...I know LitterBug has been talking about dusting off his old C skills and looking for something on dRonin to hack at
Personally I'd rather see him help out with improving GCS and OSD support. But with spring starting I suspect he'll be doing more flying and less hacking for the next few months
(and conversely with summer on the horizon I'll be doing less flying and more hiding in the AC so who knows maybe a coding project will start to sound more interesting to me soon.)
