I primarily mean for me personally and in general for us at 4teamwork as this has editor integrations available and wraps all the relevant (for us) things and seems to have a clear vision and some steam (at least initial enthusiasm) in going ahead.
For Plone this could be experimented with for any Python 3 branches or Python 3 ready packages. And I do not (most likely) mean to ultimately replace anything with coala, but to wrap it into the existing toolchains. The main value it provides is a unified interface for various tools (like pylama or pyflakes would as well, should they have an actively maintained and functional plugin for all the tools).
At this point I'm merely happy to see something new has popped up which addresses some of the Python QA stack gripes I've had for a while and I was fretting I'd potentially have to go out of my way to implement myself.
