We definitely don't want this daily! This package is stable and for the vast majority of people just works.

Adding dependabot would damage the package significantly, I'll change your changes from https://github.com/gaby/watchfiles/pull/9/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR65 and add them manually.
