To be honest, I don't know. Feeling?

I see.

Reading again bug 930935 it seems that there are still devices in
production, so age isn't a good qualifier. I put it in because it seems
I don't have much inspiration for this at this moment.

Close. https://tracker.debian.org/pkg/webkit2gtk shows that there is
also javascriptcoregtk to grep.

How about the attached version?
