Some users have been suspended from chat for long periods of time. CMs are justifying such long suspensions by saying chat isn't the main feature of the site. This is true to a certain extent, but not 100% true.
Lots of times, we fall into long discussion in comments these users (which is unavoidable at times) and chat comes to the rescue. Here, chat serves like a main feature of the site because comments aren't meant for discussion.
Now, some of the users who have been suspended from chat are old users with a high reputation who are highly active on the site. So, it is likely that we can encounter a comment discussion with those users in the future.
What to do then? Should I continue that discussion in comments until it has a conclusion and then move it to chat? Or, should we allow them for limited access to chat (access to only comments turned into a chat room, that's also for limited time)?
