Compilers already warn about this being an always-true condition.
https://gcc.godbolt.org/z/ord8vsPMW

Clang says "address of function 'wxIsMainThread' will always evaluate to
'true'" and suggest you either add & or (). GCC says "the address of 'bool
wxIsMainThread()' will never be NULL" but is missing the suggestion. MSVC just
complains that you're narrowing from a pointer to a boolean, which isn't the
best warning, but still is a warning.

I do think deprecating the decaying of functions to function pointers is the
correct solution, but the chance of this happening before the entropy death of
the universe are pretty slim.
