A bunch of us are already using 040 for production servers. We will announce publicly when the remaining bugs are smashed.
Why uneasy? 0351 works great.

I am worried if after 2 years there might be bugs or vulnerabilities with 0351 or even the Debian base... From the outside it just feels abandoned, but if you say that development is ongoing then ok.
Also I can't wait to get rid of the mdns stuff! I still have trouble accessing services from my phone in the same LAN, but from the PC they work. Just a pain in the ass...
No known vulnerabilites. Develpment is happening at a rapid pace, we are just building something huge
