I guess time and interest from community/companies are the biggest issue. Also, I usually work on new features when they would be interesting to help my daily usage of the module(s) on my own site.

I have no direct use case myself for that feature, although I admit it would be a killer feature. I've tried reaching out a couple of times, but it seems the community and/or companies aren't really interested in it, for now at least.
