There is a test matrix for Boost as a whole, right? It is documented 
publicly which exact compiler versions are tested for Boost as a whole.

I'm very much in favor of this proposal: It is clear and even has 
defined "what it means" which avoids what happened to "dropping C++03" 
or "Support CMake":

- Clean up build matrix of Boost super project
- Change documentation accordingly
- Of course individual libraries are free to do what they want IN 
ADDITION to those "officially supported" versions, but they don't have to

So I think "We no longer block releases due to incompatibility with 
these compilers." is the key.
Am I right, that currently Boost builds in all configurations stated in 
the release notes? And that a failure on one in one library will be 
considered a bug (Exception: C++AA libs which are only build on C++AA+)? 
This would contradict "Anything other than that [Latest C++/Compiler 
version] is optional."
