This is a question best answered by Christoph Lipka, however I'll add my 
(informal) opinion, and that is with 4.0 we're quite open to changes 
like this. The main constraint (if it is even a constraint) is the 
availability of free, quality compilers that meet the C++11 or C++17 
standards on all the platforms that we target.
