Yes. That is, this is the main (or actually only)
reason for asking.

I guess with a swap member, you kind of get this for free.
With filesystem::path I consider this a non-issue, though.
I mean, the time a possible extra copy takes is negligible
to retrieving a directory listing or parsing a config file
(opened using filesystem::ifstream).

No, a no throw 'swap' will suffice...
I mean, except for swap, filesystem::path
is complete enough for what I use it for.
So I obviously also don't really care about
other requirements (looking at it from a
user point of view).
