This is mostly a theoretical case. We have buildbots that compile in C++11 and ran tests for a 
couple of years now (and one in C++14). And by default (since GDAL 2.2 I think) ./configure 
already enables C++11 on all C++11 capable compilers.

There are perhaps a few niche drivers that depend on third-party SDKs and that people have 
not compiled in years, but they might be broken in other aspects, so not much of a concern.
