At a minimum, perspectives play very nicely with the plugins system.

Eclipse was created over that extremely interesting idea that you can write a plugin to do some completely random task, and have all of it reconfigured on the perfect way for that task.

But you can't have a rich ecosystem of plugins without organizing them in some way, and nobody ever created a Debian-like system for them as it's a lot of thankless hard work.
