@erral what's the state here?
sounds like a useful feature!

[erral]

It is a proof of concept and needs more work and more testing.

If this should be shipped with Plone 6 it needs to be finshed soon.
We want to fix the test now and merge into master soon.
But it can also be merged into master later, as long as we are not in Plone 6 beta.

[erral]

I would like to but I have no time to look at this in the coming weeks.
