I'm guessing there hasn't been opposition on this thread because the users that this might affect aren't following this mailing list.
I'd be interested to see which other major C++ projects out there have bumped their requirement to C++17, and how that experience was for everyone--the user community as well as the developers. Do you know of good examples? I just checked on CRAN today, and of the 17,694 R packages there, only 3 require C++17 (none of which have wide adoption) and only 20 require C++14.
