Would your plan to be to just keep twisted pinned until you can EOL ubuntu? I 
don't want to be putting (non-trivial numbers of) users into the position of 
having to skip a bunch of updates.

Yes, I'm already working towards EOL of Ubuntu 16.04. I expect to have that 
work completed by the end of the year.

In the one case that may be complicated I think that pinning Twisted will be 
acceptable, since the service in question is a process supervisor without 
direct external exposure.

Glad to hear it :).

Well in that case I'll just do my best to add lots of goodies (posix_spawn 
support!) that will make you want to upgrade that to current twisted and python 
3.8 :).
