Recently, there have been some discussions on #boost-gil
at cpplang.slack.com and in comments on GitHub issues
about switching GIL to C++17 
TL;TR: Shall we do the switch and when?
We are a small team with limited time and man-power at our
disposal and we need to spend it wisely and effectively.
The development comfort and convenience has already been
improved by the switch to C++11, but there is still more to gain.
e.g. Samuel is one of users and active contributors (joined the
team lately), with very interesting ideas how to improve GIL.
>From the point of view of plain GIL attractiveness due to
succinct and expressive C++, availability of complete standard
library and no fuss with maintaining support for compiler
(e.g. five years old GCC 5), I'm very keen in making his and
everyone else's time-limited work easier and more rewarding too.
So, paraphrasing Peter Dimov's sensible suggestion  and
according to the Boost release schedule :
We may declare C++11 support deprecated in Boost 1.75 (December 2020)
and drop it in Boost release (1.77?) in August 2021.
I think it is a feasible plan with outcome not too distant in the future,
and GSoC 2021 could allow C++17 too.
I'd like to hear if there are any strong objections.
 C++14 is not under consideration
