That might work. Rather than calling it a bug report or feature request, it could be framed as a simple support request. You wouldn't be asking them to change anything about their software, just to explain how it works so that you can configure it to meet your needs. That information might then be useful to FF forks, or individual users, who may prefer for that configuration to be part of their default.
