I remember using it all the time for the Windows headers because they pollutes the compilation unit like you wouldn't believe — the rule was to only include them in c/cpp files.

We put
In precompiled headers to solve that particular problem.
That's kind of a hack, still best only used in implementation files, not headers.
The irony is that including/using many standard c++ headers is far far more expensive than including a lean windows.h these days.
To make hobby-coding fun, i use a mstdp.hpp that implements "naive" versions of unique,shared,function,etc that compiles faster than including just one of the std versions (and yes, MSVC versions of those libraries seem to be excessivly complex).

That may be true, but it's a "hack" that has caused me approximately 1 issue in 15 years of writing C++ professionally, and that issue was a problem with our build system not the precompiled header.

We only compile implementation files!
