Unfortunately most of that doesn't really matter for any non-trivial project, because you'll almost unavoidably need a module for something. A lot of the time you'll find out that it's bit rotted 5 years ago, and the bug tracker has a 7 year old issue nobody seems to have read.
It's even worse for anything that interacts with libraries or APIs -- those change over time, and often nobody does the work to repair compatibility.
So I think at this point it's fair to say it's dead. Even if the core language is technically functional, the ecosystem is rotting.
Perl doesn't need an ecosystem any more than the Almquist shell does. It's just a nice tool that's omnipresent on UNIX systems. It's definitely going to be useful for shell scripters for a very long time.
