On wordpress.org, what is the logic behind closing support tickets permanently?

Even moderators on wordpress.org can't reopen tickets:

https://wordpress.org/support/topic/can-i-open-a-closed-for-reply-topic-as-a-moderator/

This is weird and stupid. The question for SE is:

Has Automattic expressed the reason WHY they do this? Can you provide a link to trac or a blog post where they explain themselves?
