AFAIK that's true for all the proposed users.

For very rare and obscure cases like this in my experience
the simplest possible code is the best,
that makes it most likely it actually works when it's needed.
I do not know of any simpler way to implement this.

Of course if there's evidence it's actually common that would
need to be revisited.
