Sort of, you get to close stuff faster if you have auto close after solved, cause you would likely set timer a lot shorter.
For example, in our Support category I would set:
“auto close after last reply” to 2 months
“auto close after solved” to 2 days
You want to give people a chance to necro a reply to a support question to a degree, but once it is solved, you want to close it pretty quickly.
