I expect to drop support for 8.x.0 soon (maybe with Buildbot-0.9.0?),
but that will only bring us up to requiring Twisted-9.0.0.  My reasons
for doing this will be:
 - new features or code which require a lot of workarounds for 8.x.0
but work with 9.0.0; or
 - general unavailability of 8.x.0 (for example, I couldn't find a
copy of Twisted-2.5.0 to test against a few versions ago, so I dropped
support for it)

If Pierre's work can be implemented in such a way that it safely
disables itself on older Twisteds, then the increased version
requirement would not prevent me from merging it.
