This is a good point.

One of motivations is to drop support for GCC 5,
It just seem simpler to assume C++17 as requirement
with comment that some compilers w/ partial C++17
support may still work.
It may also be possible to list required C++17 features
per Boost (GIL) release, but that list may change
in any next release, obviously.
