As a consumer, it's already hell. You'd be adding a grain of sand to a beach. :)

The only way to get rid of the bad interfaces and unmaintained modules is to upload good interfaces that somebody will maintain. That the space is cluttered with crap shouldn't keep out the good stuff. Once you upload, I can say "Don't worry about remembering the name, just use the one Ovid wrote." :)

I agree, the pollution isn't really an issue at this stage. I don't really bother browsing CPAN at all. If I need a module for a specific task, I simply ask other people for recommendations. The cream does rise to the top; a good example is with date modules. A couple of years ago, there was a huge slew of them, all with various pros and cons, and most with some issues. Now, I wouldn't really think of using or recommending anything other than DateTime - it's the DBI of date modules.

If there are major issues with existing modules, then I don't think people can complain if you release another one. Especially if you can't get the existing modules patched, and you put a note in the POD saying something like "Why another XXXX module?" and clearly lay out your reasons for re-inventing the wheel.
