constexpr are implicitly inline, so these two don't actually work
independently. At a minimum you must ensure that the former is visible before
the latter. Or write extern constexpr.

What's the point of an extern constinit without the initialisation? One does
not need to know how to initialise this variable to use it. And without the
initialiser, how would the constinit keyword make any difference in this line?

So, is this different from the case above?
