One package author [as in user of Rcpp and not an author of it] was told by CRAN this week to change his package and came to me for help -- so in that small way the CRAN "non-communication policy" is already creating more work for me, and makes me look silly as "I don't document what Rcpp-using packages need" as I sadly still lack the time machine or psychic powers to infer what may get changed this weekend. | More importantly, I don't think that the requirement is necessarily to | change Depends: Rcpp to Imports: Rcpp, the requirement is to put | imports(Rcpp) in the NAMESPACE file.

We also only about two handful of functions, and those are for functionality not all 135 packages use (eg Modules etc). But the focus here should not be on my hobby package. The focus needs to be on how four CRAN maintainers (who do a boatload of amazing work which is _truly_ appreciated in its thoroughness and reach) could make the life of authors of 4800+ packages easier by communicating and planning a tad more.
Let me paraphrase that: "The CRAN maintainers do a lot of work, and it helps me a lot, but if they only did a little bit more work it would help me even more."
I suspect they'd be more receptive to suggestions that had them doing less work, not more.
