The answers are: no, yes.
wikilib.d is the directory for "precanned pages" that come with PmWiki.
It's the place where updates to the documentation go. With every update
to PmWiki, there is a risk that the new distribution will accidentally
have a page with the same name as yours, and then your page will be
overwritten (there won't even be a change history from which you could
resurrect the page).
Of course, it's very, very unlikely that wikilib.d will ever by
distributed with pages in a DufferinParkWiki group ;-)

It's the way that PmWiki works. The intent is

755 is better because it limits write access; a 777 directory can be
overwritten (i.e. the files in it renamed or deleted) by everybody with
a shell account on the machine.
Whether the permissions can be fixed or not depends on the Apache
configuration and its setup for PHP. Also, whether the two directories
are handled the same (and thus can take the same permissions) depends on
whether they have the same owner or not.
