That's the most efficient, yes (and also what we do in the RTL).
Alternatively, you can manually create the wrappers in the
implementation (so you add separate external declarations in the
implementation and then call these from regular Pascal implementations
of the interface definitions), so the compiler doesn't do this for you
and subsequently change the interface "declaration" into the external
