Obviously it can't. I just missed the fact it was virtual because it's
not declared as such in CoordinateArraySequence. So I believe the
compiler was only able to inline it when it was used explicitly through
the exact type. This explains why the cost remains visible (indeed if it
was totally inlined I didn't expect to see it in the call graph anymore).
