[tor-dev] Proposal: Controller events to better understand connection/circuit usage

Certainly could. I left the CellType alone (both leaving it as
lowercase and a string definition) because it's a sub-mapping and
hence we don't have any precedent for those. On reflection I agree
with you, an uppercase enum would be more consistent.

I'm not sure what 'previous' and 'next' are in reference to, and
AppWard and ExitWard aren't any more illuminating. That said, I'm not
the target audience for these events so if you think any of those are
good descriptions for the users of these events then go for it. :)
