If there were a tool available to do this, that might resolve many of the
remaining issues here. But I suspect doing this automatically is Hard.
By the time the library has been generated, there's no real way of knowing
whether the symbol was inline or not. You'd really have to somehow
generate the symbols tags as a side-effect of the compilation process.
And obviously doing this by hand by manual inspection when there are over
12,000 exported symbols is infeasible.
