It s a dialect continuum so the boundaries are going to be somewhat arbitrary But for some odd reason the dialectological work necessary to minimize the arbitrariness doesn t seem to have been done in India and right now this seems to be a particular problem with greater Punjabi I have come across apparently RSs that treat Saraiki as a language though most seem not to I could care less personally I just revert people because the argument seems to have more to do with politics than with language and because it s being argued through ranting and edit warring rather than sourcing and serious discussion It s currently at dialect because last time there was a real discussion those advocating that side were more reasonable and better sourced but that could change and I d have no objection if it did
