Yes, it's maintained, and I've even written a package that uses it
(testthat - both it and mutatr are available on cran).  It's still
mainly an experiment, and I don't currently have any plans to give up
using proto.  However, my entirely personal perspective is that my
code seems to be cleaner when I use mutatr instead of proto (this
probably reflects that I wrote the package though!).
