Still, as it came up, this argument raises the interesting question what
will happen to users of the clang code model that cannot switch to
(non-standard) pragma once for this or that reason?
What would it take to fix this problem? Can we work around it? Can we
provide an upstream fix?
Apart from that, I did not understand the problem at all.
The opening #ifndef does match the #endif, doesn't it?
If "matches" means "is balanced with" at least.

Sure, let's give users the possibility to choose between include guards
and pragma once.
