The biggest and worst issue is the semantics are total unmaintable
garbage and there has never been a single counter argument to that.

Recursive delete is WRONG.

Further there was no follow up converstion on the list about this trash
to say you had tested it.  Or anything else.

Even the partial recursive delete we currently have has been responsible
for broken users of sysfs so I don't see how adding additional checks is
going to do anything but paper over real bugs in real uses of sysfs.

Will you please remove that garbage from your tree.
