The only reason it was implemented this way is because bash is still
essential and so does not need a dependency.

Well, we only guarantee to support upgrades from stable to the next one.
Obviously we will try to not break things in unstable and testing.
Though it's not uncommon to make the assumption that users have at least
upgraded to stable before doing partial upgrades to unstable/testing
versions.
Anyway, using a really old packaged bash, a newly packaged bash or a
self compiled bash (even the version in lenny) should all work for this
/dev/tcp use. It can also be replaced by 'lsof -i :111' or something
netcat like, though for both these you need to make sure you have lsof
or netcat installed.
