At least the BTS automatically reopens the bugs so the problem doesn't
stay unnotified and untracked.

The maintainer is still king and if he decides that the NMU was not a good
idea, he would have no other choice than skipping a revision in the
changelog. That would be confusing.

Furthermore, as we encourage usage of the delayed queue, it seems natural
to avoid collision between the NMU upload and a maintainer upload
integrating the NMU done before the end of the delay.

IMO you're trying to abuse the version numbering to avoid a problem. The
problem can be detected automatically (the BTS does it!) and it should be
possible to have an infrastructure to inform the maintainer if what's
existing is not enough.

I'd like to remind that if the maintainer had given a look to the PTS they
would have seen the NMU. The PTS displays a prominent notice in the TODO
section "you should integrate the NMU".

A look at the BTS also gives you hints about the existence of the NMU.
Those hints would be even more visible once version numbers include "nmu"
in them. Then the maintainer also received several mails about the NMU
upload.

It works well except when the same package version is in two consecutive
release.

1.0-1+sarge1 > 1.0-1+etch1 when we really want the opposite. That's why
this scheme was invented. I agree that it's not very nice though but i
couldn't find anything "cleaner".
