Short description of error
When Storing a color attribute [on the point of facecorner domain] and have the attribute overlay enabled the object appears black in the viewport instead of showing the color like usual
(other domains are not picked up by the overly)

Thanks for the report. The behavior did change here, and it might even be less convenient now, but I think it is correct. The "Attribute" overlay is meant to show the active color attribute. Adding a color attribute with the Store Named Attribute node was never meant to set the active status for the attribute it adds.

Not sure, then no regression?
Should this be flagged as a known issue since the old functionality is gone now and may come in the future via the active slot setup functions?

It's definitely gray area. It's a regression because it's not possible to use the overlay like before, but it's a bug fix because that was never intended and was inconsistent.
Since I don' think there's anything to do for this report in particular, I think I'll archive it actually. I'll mention it in chat though, in case others view it differently.

I use this to color my geometry in the viewport and in the workbench render.
do you think we'll have more support for attributes being used like this some time soon?

Workarounds for now are using the viewer node, adding a material that uses the attribute, or adding the color attribute on the original mesh (in the mesh properties tab) and making sure it's active there.
I think one of those should work in this situation.

I was thinking off the last one. i just haven't tested it yet.

I just tried it and i have to use a join geometry to make it work with generated geometry
