Sorry for being a killjoy and repeating myself, but as mentioned in
the past, I don't think that technical direction is the most important
problem right now - community is.
Coming up with medium/long-term technical roadmap doesn't do much if
there are no contributors to implement them, and users to use them.

The following issues which have been brought up are still not resolved:
- very few committers willing to review and merge MRs - currently only
Andrei Sekretenko is doing that, and I'm sure he's busy with his day
job so only has that much bandwidth
- very few people contribute MRs and triage/address JIRA issues -
AFAICT it's pretty much Andreas and me

So I think the first thing to do would be to address those problems.
Some suggestions which come to mind:
- to the remaining committers who'd still like to salvage the project,
please take some time to review and merge MRs -
https://github.com/apache/mesos/pulls has a few open, several fixing
bugs which basically make Mesos unusable on a recent Linux distro
- to the various users who've said they were interested in keeping the
project alive: start contributing. It doesn't have to be anything big,
just get familiar with the code base:
  * start going through JIRA and triage bugs, closing invalid/stale
ones, tackling small issues
  * submit MRs so that the test suite passes on your OS
  * submit MRs to merge various commits you have in your private repos
if applicable

Then in a few months, once the project  is back to having a small
active contributors base, they can together decide how to take the
project forward, and start addressing larger projects.
