None for the moment
Gotta bump this number whenever you change s_defaultFileExcludeFilters
This one makes me a little nervous since it's a not-very-uncommon English word, not something implicitly technical that we can be safe excluding.
Is there any other way we could exclude the contents of these folders? Maybe by filename, mimetype, or the naming of sub-folders?

This directory contains only pure PHP code, so not possible by filename or minetype. Maybe we could use the fact that a composer.json is always included in the same directory?
PHP source code files are already supposed to be getting excluded though (search for application/x-php in this file). Are the PHP files in question using a different mime type?
