When Standard C++ finally made it out it didn't use any of these convoluted attempts at something different from C's .h, rather it just dropped the extension entirely.
Compilers just open files that are specified via #include without making any assumptions, so you can use absolutely anything you want, you could use .CPlusPlusHeaderFile if you wished and it'll still compile. Back in the late nineties I made the choice about extensionless header for the OSG as it aligns itself with what the Standard C++ headers convention, rather than going for one of the many .yetanotherabitaryc++headerextensions that were proliferating at the time. Back then I wouldn't have thought that it'd take more than a decade for IDE's to automatically realise that an extension C++ header file is a C++ header file.... for all the sophistication of modern software some really dumb arse things aren't possible...
