Re: [SG15] [isocpp-ext] [isocpp-modules] Modularization of the standard library and ABI stability

Note that MSVC has been experimenting with modular views of the standard library since late 2015, and the paper I cited earlier was based on that experiment.

As I recall, we did not have consensus to evolve the ABI at Prague.

As a reminder, these were the polls:

3. From now on, we should consider incremental ABI for every C++ release

Could someone who was there, please tell me what this poll's text means?
What does "consider incremental ABI" mean?


P.S. — Back on the question of "how should a modularized STL look," personally I think that's an area that should be pioneered by practitioners — library-writers and library vendors — not by ISO on paper. Are the libstdc++ and libc++ communities actually investing in an attempt to deliver a modular STL? If they're not, is it just for lack of manpower? Is any third party currently working on a modular STL, the way we saw third parties working on `fmt` and `range-v3` and ASIO and Boost?
