I very much doubt upstream are going to accept anything like it
unfortunately. Whilst much of the information is useful to plugins, I'm
struggling to see how/why they'd use line numbers outside of debug
information so I've assumed so far they're just that - for debug. DO
you know of it being used in other ways?
