The RFCs for this library (initially two, merged into one) have been up since October, during the 16.11 timeframe. Comments were made and applied.
I'm concerned that these new comments/reservations are coming in very, very late in the 17.02 release cycle.
If there hasn't been a lot of opinions or enthusiasm then equally there hasn't been other reservations. If there had been we would have addressed them.

We are happy to have the design discussed at the Technical Board. We would also like the inclusion of this library in RC3 to be discussed since that is still our desired outcome.
We have, as any other company would have, customers awaiting features, developers committed to timelines, and testing and integration roadmaps. Blocking or delaying features at the last moment isn't an effective model that we, and I'm sure other companies, can work with.
As such, it is probably best, that all current and future RFCs are reviewed at the Technical Board and that the board gives an indication on whether the proposal is acceptable for upstreaming or not.
> The overview for using this library should be given in the prog guide.
We will add a section to the Programmers Guide.
