It isn't at all, but it has the rather large problem that it breaks the
API :) All existing {{result}} entries in all pages will be invalid.
That seems like a deal-breaker. We're kind of locked forever into the
first five fields being 'result', 'username', 'bug#', 'bug#', 'bug#', I
think, to preserve existing results.

I had a quick look and I suspect you can, but it'd get really pretty

Yeah, I can see the thought process there.

I guess another problem here is it makes the process somewhat more
complex; right now we have a fairly simple SOP for doing a test release
event, which is 'create the results pages and send out the mails'. I
guess it becomes 'decide whether to create a new results page, if so
name it according to this new naming scheme'. Not that bad, I guess, but
a bit more work. How did you envisage naming the pages?

(it also means you can't reliably find the correct results page by just
plugging the appropriate fields into the known format, I guess, unless
we're careful about setting up redirects.)
