The motivation for my work was not static initializers, but avoiding any implicit conversion from const char * to avoid calling useless strlen.
The constexpr part of my work came to avoid having to make the explicit call for literals.
Being able to have global table of StringRef was secondary to me, even though it also saved some scanning when performing lookup.
