decision not to expose peg revisions in the UI as it just complicates
things. There was also a time where a lot of the API's did not expose
this parameter to us. That could even still be the case here. I
think you should file an issue so that if we are running blame against
a specific revision that we should default the peg revision to be the

What context in our UI did you take this option? One of the reasons
we default to HEAD is the assumption is that you are working at or
near HEAD. So if you Show History on an item, the option you took is
