No, it's not.  It hasn't been touched for almost two years so I forgot
about it.

Does it still apply to current mainline?  Will it still work correctly
in conjunction with the Windows 10 1709/1803/1809 changes in terms of
deleting and renaming files?

More importantly, I'm not confident to maintain this code alone since it
won't be used most of the time and it adds a heck of complexity to
handle a border case.  Will you be available to maintain this code for
the forseeable future?  If not, the code won't go in, sorry.
