I think I'd like to rise priority to Critical for this one. It might require rather ugly work-arounds in sbt code which is very hot. I'd prefer to not complicate logic in hot places for performance reasons.

You mean you'd like to have this fixed in 2.11.0-final or 2.11.1 would be enough?

@gkossakowski said:
I don't think it's a blocker for 2.11.0 release.

In 2.11.1 should be enough. Actually, given the fact I realized it's not that bad for performance then keeping it Major should be ok. However, this original field is quite important to tools like IDE so we should fix it eventually.

Looks like this was fixed on the sbt side? Can you still repro with sbt 0.13.8?

Here are some of the PRs that seem to fix this issue:
sbt/sbt#1237
sbt/sbt#1408
sbt/sbt#1563
sbt/sbt#1642

presuming fixed, since no one has said otherwise
