Okay, good.

I know about these tricks and have used them for other packages.

For all dependencies that respect semver there is usually a reason for 
major version jumps, so patching out the check is not a good idea. 
Otherwise the specification in Octoprint does not cause problems as it 
already allows minor updates. Also I would rather not cause tons of bug 
reports from people using unsupported versions.

Creating extra packages to pin versions works of course, the problem is 
just the huge amount of runtime dependencies:
Making 1 or 2 extra packages does not cut it here, maybe with 10 (at 
least tornado, flask suite, click) it could work momentarily, but then 
there are still 30 others that increase the likelihood of breaking. In 
the past it never worked longer than a few weeks before it required some 
action/fix again.
