My thoughts, fwiw - school holidays have just happened. Also, bills need to be paid. So there is likely to be some overlap between family life, doing other things to pay bills and being busy updating cache / producing a white paper.

Vertoe was silent during the first few weeks of announcing to take on cache, then there was a big release.

S/he didn't notice the fork, but a fix was pushed to the git and somehow merged with Vertoe's repo. So, S/he is still around and so I'd expect some update, when its ready. That's the 1m cache question. 1 day, 1 week, 1 month or 1 year 2 months.  I'd guess, a few weeks to a month or so.

If you want to contribute, read the OP. Looks like github is the place you should be placing ideas, requests, etc. If you have some cach and you're on the right fork, I'd guess Vertoe would say you are the community, go get a git account if you haven't already got one.

Just my take, again, fwiw.
