Vanilla vim is like compiling - efficient, but with a huge upfront investment. A vim 'distribution is like JITing - you end up at roughly the same spot, but it actually lets you do the thing in the meanwhile.

I think this only works if we allow that JITing is harder to understand and improve, because distributions tend to be opaque.
