I agree, that naturally follows from connecting the dots. Hence my
desire for having such a facility available not only for the standard
library but for similarily structured named modules as well.

I really hope that this will become reality. Having that would be a huge
win for the community at large: every #include of a standard library
header would be synonymous to import std; 😊 And every source would gain
by taking advantage of a modularized standard library without having to
change anything and transitioning to import std; could become a non-brainer.
