Huh, macOS includes a utility called `dot_clean`. It's just been sitting there, quietly, in `/usr/sbin` for decades waiting for me to discover. I've been using macOS since it was OS X and thought I knew most of its nooks and crannies. Today I learned a new one. When I was first introduced to Unix in the mid-90s, one of the things I did was to poke around all the bin dirs, see what was there, read most of the man pages. I'm not sure I ever bothered to do that on OS X. Maybe it's time.
