open_basedir is only relevant for plain files, so there is no need to check it for other URL wrappers.

If that's the case, shouldn't it be part of php_check_open_basedir itself?

Somehow that would be better, but it seems that a lot of related code assumes otherwise, and I'm not sure about the performance impact.

Bad wording, sorry! I mean that some code already checks whether a plain_files_wrapper is given, and only then calls php_check_open_basedir(), e.g.
php-src/ext/standard/filestat.c
Line 778 in 1bc56db
