I'm interested in this effort and would support it but at this point I am extremely concerned about the overall support from Securifi wrt A+.
Should this change, issues with Realtek/OpenWRT improve, Apps stabilize, things like light bulbs don't break with a major firmware release, then yes, it would be worth the effort.
For now, imho, it's a wait and see. Which is pretty much what I have been doing for 2 years, sadly.
