Comment (by nickm):

 So here's my tentative opinion:

 1. Log messages are not intended to be machine readable, and parsing them
 is always asking for something to break.

 2. If you find yourself having to parse a log message, then we are missing
 some kind of feature to provide the information in some other way, so that
 you don't have to parse the log message.  So the bug might be ours -- we
 should not assume that applications doing this are being wrong, but rather
 that we are forcing them to be risky.

 3. We could make status events available even earlier, via the
 OwningControllerFd interface.  We might want to have a new option that
 sets the initial events (like SETEVENTS) on the OwningControllerFd, if
 that would help.

 4. If there is not one already, there should be a GETINFO command that
 returns the current bootstrap status, so that you don't need to see all
 the previous bootstrap messages to learn how bootstrapped Tor is.

 None of these feel like blockers to me, though.  If folks don't disagree
 too strongly, I'll have a look at this code and probably merge it.
