{quote}I mean if some application expects PathIsDirectoryException to be thrown
for touch command used with directory, from that viewpoint this behaviour
change might be treated as incompatible?

Thank you [~vjasani] for your comment. It makes sense to me, so I will add a
release note to warn the users. Anyway I'm not a fan of adding a new option
because the option is not consistent with the touch command in POSIX.

{quote}be interesting to see which filesystems don't like this
{quote}
Filesystems that don't implement fs#setTimes are the ones that don't support
touch command anyways (for files), and that would be the same case with this
improvement as well (for dirs).
