There may be some potential issues when hosting Python in a C++ app built with a later version of MSVC, since vcruntime140.dll is predominantly initialization and exceptions for C++. I can't think of anything specific here though, and it seems likely that the host's initialization code would apply for the host. The C Runtime doesn't rely on anything initialized here as far as I know - it's only the C++ libraries.

Shouldn't be any other implications other than slightly easier distribution and slightly larger file sizes. (Haven't actually checked how much larger, but it is no more than 10s of KB which I consider acceptable.)
