I suspect it means to support >=C++14  compilers only.

Not for me. For me it means it uses ar least one C++14 feature and needs 
a C++14 compiler. The library doesn't supports C++11 compiler nor C++14 
compilers that don't support the used feature.

This one. This doesn't mean that it uses all of them, just that the 
author wants the freedom of using them.

No in my view.

Tell me if my alternative view of what "C++14 only" could mean change 
your view.

Wether we want a "C++14 only" Boost  version is another thing.
