..if you still worry about the ways "apt-get dist-upgrade" want to do
things, try e.g. "aptitude safe-upgrade", "Perform a safe upgrade", 
or "aptitude full-upgrade" "Perform an upgrade, possibly installing 
and removing packages", these will often solve these things at least 
slightly differently to apt-get.  
And there are many other ways to do this, me, I spent my last coupla
Debian years in Debian's dpkg version of the rpm dependency hell I 
endured in my Red Hat 5.2-to-7.3 years. ;o)

..for _some_ people, this worry is not just about "whether Devuan
Jessie works", this is also about whether they have a job and can 
pay for their childrens food and home the next few months.  
Which is exactly why they stuck their neck out and recommended 
"rock solid" Debian Wheezy _LTS_, years ago when it was rock solid.

..and it's why I voiced my idea of a "Devuan Wheezy LTS 0.x" style fork.
We can expect these people to volonteer work for us like what they 
have for debian.org, once they see us as a viable way forward for 
themseves, careerwise and financially.
