Are you interested in file input support PRs?

[srvance]

I've implemented a makeshift file input component in our code, but it's not as good as I'd like because of some limitations in the Formik design, such as field validators only taking value and errors setting value if you use Field. I have a pretty good idea of how to create integrated support (e.g., having field validators take an optional second argument of either files or target), but want to make sure you're open to that as a PR before I put in the work. What do you think?
