I don't thing this is remotely true. C++ pragmas were designed with the express purpose of providing additional information to compilers.

Attributes are better suited for that. #pragma has always just been a grandfathered in hack.

See for instance how Visual C++ uses pragmas extensively to toggle specific compiler warnings, not to mention the infamous #pragma once
