This is sadly false. The static member function which uses pool_ may get
inlined in the using TU thanks to being defined implicitly inline in the
class definition.

At link-time, the user will not be able to resolve the symbol, even
though the library exports a symbol by that exact name, thanks to how
exported symbols are implicitly indirected one layer.

I tried that approach first, and it didn't work.
