--- Comment #17 from Reid Kleckner <rnk at google.com> ---
I think we can call this fixed. Bob added the feature of not touching the .lib
import library if it hasn't changed. We don't have any other plans to work on
incremental linking.

Over the last year, I managed to parallelize ghash and significantly reduce PDB
linking memory usage. I don't have lld-link /time output ready to paste in
here, but I think we can claim that the situation is much better than it was in
2018 when this was filed.
