Boost.JSON is not advertised as a nearly header-only library. It's advertised 
as a library that supports header-only use. By default it is still compiled as 
normal. I've checked Debian Sid package search and I can see that it uses 
Boost 1.74. JSON only appeared in 1.75, so that's why there's no binary on 
your machine.

Looking at where the winds are blowing in this discussion, we'll have to 
indeed add a string_view implementation to Json. Problems with other 
approaches were already presented by Peter, so I won't repeat them. So, there 
will be (at least one) new string_view in Boost, just not in Core.
