As I said before, for my opinion, I think we should move to msvc-15.0 for the toolset, as that will be *less* confusion for the end-users.
I disagree - 15 is the IDE's version number. The IDE can host multiple toolsets (already it can install v140 and v141; expect more in the future).
In the past IDE and toolset version numbers were equal weren't they?
Another approach would be to give up on the 14.x version numbers entirely (admittedly it is confusing to have the v141 toolset linking against msvcp140.dll for bincompat). Instead, use _MSC_VER as the toolset identifier - this is 1900 for VS 2015 (RTM/Updates) and 1910 for VS 2017 RTM, and will increase in a fairly predictable, monotonic way in the future.
Can't MS use a single version number for the compiler *and* the toolset? -- Olaf
