0-day NMUs for RC bugs without activity for 7 days?

A patch was proposed (#625449) to implement in dvelopers-reference the
"DELAYED/0 for upload fixing only release-critical bugs older than 7 days,
without maintainer activity for 7 days" policy.

I don't think that this policy is a good idea. But, since I was one of the
drivers of the DEP that resulted in the current NMU policy
(http://dep.debian.net/deps/dep1.html), I'm a bit biased, and I thought I would
bring this proposed change to the attention of -devel@, so that we can get more

Reasons for which I am against the change:
- In addition to giving some time to the maintainer to react, the 2-days delay
  also gives a chance to debian-bugs-rc@ readers to review the diff.

- The dev-ref documents the "default" choice. While there are cases where I
  agree that uploading the fixed package ASAP is necessary, in most cases, we
  can probably survive two more days with the bug, if we already survived more
  than 7 days.

- Doing an NMU without trying to contact the maintainer beforehand could be
  considered an aggressive behaviour, or a way to "punish" the maintainer for
  not addressing bugs as fast as one would like. We are trying hard to fight
  the feeling that NMUs are an aggression, this could be counter-productive.

- I don't think that it documents the current practice. Looking at the archives
  of debian-bugs-rc@ in 2010, there are 390 mentions of "DELAYED/2", vs 711
  mentions of "DELAYED", so uploading to DELAYED/2 looks quite popular.

- Developers could be tempted to "ping" their RC bug reports every 7 days to
  ensure that someone would not NMU their packages without prior notices. With
  1815 open RC bugs, this could add some noise ;)
