In the perfect scenario, I suppose Lilypond would "Do The Right Thing":
   1. If there were another music event at the moment the Hairpin  
was set to begin (delayed) or end (trimmed), it would line up as  
expected.
   2. If there were no simultaneous music event, the Hairpin would  
begin/end proportionally between the immediately adjacent music events.

Probably... =(

I just think that dynamics are currently more difficult to manipulate  
than would be ideal, and I'm trying to come up with a solution.
