If you have been working to resolve things upstream, then now’s a good time to mention it. Because as far as I know, all of the major problem with Flakes are still as unaddressed as they were years ago and I have not seen any contributions by DetSys in that direction, but maybe I just missed it?
Yet the RFC was closed due to lack of interest. If you knew about it, why not help out with such efforts? Similarly, I also don’t recall anybody from DetSys participating in RFC 136 (not that it’s a big milestone, but it’s going in the right direction).
