No, the current 'Standard' mnemonic is not used by the 'cxxstd' change. 
Instead create a new mnemonic called "C++ standard minimum level" with 
the value of 03,11,14,17,20 depending on the value of the meta file json 
field 'cxxstd'. If the meta file json field 'cxxstd' does not exist in a 
library's meta file, the value of 03 is assumed. Currently I have only 
attempted to update the meta file with the new 'cxxstd' field and 
appropriate value for libraries whose minimum support is C++11 or above, 
with PRs. I am still waiting for four of those libraries to merge their 
PRs on the 'develop' branch:

callable_traits
coroutine2
hof
hana

There has also been a suggestion to remove the 'Standard' mnemonic 
entirely from the documentation for each library, since its previous 
usage is out of date and has been totally irrelevant for a long time 
now, and therefore ignore or remove the 'std' meta file json field. I am 
in favor of that also, but others may be against it. I would also not 
want to reuse that 'Standard' mnemonic instead of the more precise one 
of 'C++ standard minimum level', which is easily understood. If someone 
would like to argue for 'C++ standard minimum level required' that is 
even better but may be too long.
