Any updates on this? It's still broken in 1.4.86.

Currently I work around the issue by manually editing the drillneck every time I do a complete re-import.

Probably he is busy, I think he can not afford to confirm the PR.
I will close PR to concentrate on his development.

Well, it is about time this was fixed! I may need to tweak the tags, though.
