A quick search on github for "#pragma region" comes back with 170k C++ results
and searching for "#pragma" comes back with 38M C++ results
Possibly not the best metric, but we can "conclude" roughly 0.45% of
open source C++
code files on github

#pragma region is a feature introduced by Microsoft in order to allow
manual grouping and folding of code within Visual Studio. It is
entirely ignored by the compiler. Clang has supported this feature
since 2012 when in MSVC compatibility mode, and enabled it across the
board in 2018.

This was an intentional omission - when looking for documentation of
the pragma in clang I found none.
If we do want to document the pragmas in GCC:
- what section of the documentation would that go in?
- gcc/doc/cpp.texi, section 7, "Pragmas"
#pragma region is a feature introduced by Microsoft in order to allow
manual grouping and folding of code within Visual Studio. It is
entirely ignored by the compiler. Clang has supported this feature
since 2012 when in MSVC compatibility mode, and enabled it across the
board 3 months ago.
