Good to know, thanks.
I guess we have a difference in opinion here, surprise!
How is it obsolete and pointless to archive if the plugin still works and is being used today by many customers?
Usually the description of the plugin contains important information, such as what the commands and permissions are, how the plugin functions, what the dependencies are, info about config and settings, etc. This information is not readily available anywhere else.
I think there is valuable content in discussions and support tickets that shouldn't just get deleted and that could still be useful to those of us running the plugin today, even if it is no longer supported or available to download.
Plus, I think it would be good to know that the plugin is no longer supported/available as opposed to searching multiple sites trying to figure out where I got it from only to come up empty.
Again, this seems like another decision that is not at all customer-friendly and is entirely in the creator's best interest and based on how you replied, that you are not actually open to getting feedback on.
