I am also -1.

I had occasional to speak with someone very involved in Rust development.  They have a process roughly similar to our PEPs.  One of the things he told me, which I found very interesting and have been mulling over for PEPs is, they require a section in their specification discussion how any new feature will be taught, both to new Rust programmers and experienced ones.  I love the emphasis on teachability.  Sometimes I really miss that when considering some of the PEPs and the features they introduce (look how hard it is to teach asynchronous programming).
