I picked up on this project from watching Ales' talk at JUDCon.

It seems to fit well with the vision to support other metadata providers in Seam Config. Perhaps it wouldn't be too much work to remap the logic in the extension observers to the same mechanism that the existing XML provider uses (some of which now lives in Solder).

Would anyone be interested in playing with this, or reaching out to the author and getting it brought under Seam Config?

I can ask Alen to have a look.
But he might be too busy with his studies and work.
I'll let you know his response asap.
