"They both absolutely have their place and can co-exist."

I mean... in the current architecture they can't co-exist on the same page, as comments cause the talk page to redirect back onto the article (even after the extension is disabled, if you try to go to the page a comment is on, as I found out when trying to archive all the article comments on the newly available article talk pages after disabling the extension).

They do serve different purposes and those purposes can co-exist in different areas, but technologically (at present, no opinion on the upgrade as it's not available yet), the two options categorically cannot co-exist unless something's changed since I disabled it.
