Good point.  I mainly use syncthing as a "stuff I need on multiple
machines" bucket, rather than a big directory of active working files.
Think more along the lines of "I saved this PDF on my PC but I'll need
it on my phone tomorrow so it goes into the Special Folder" kind of use
case.  As such it might not be the right fit for "synchronise a file
system" use case.
