Quite close. Pretty much everything that happens with this extension
is described in
Doc may need some love to make it more clear.

Parking tickets is not implemented.

When ticket is re-opened than old values are returned. So resolve
deadline returned to old value. I think it's correct. This depends on
what happens and what you expect from that. For example if customers
often reply to old tickets with new problems then you should use new
tickets for that, in this case forking into new ticket may help. If
customer replies to a closed ticket then problem has not been resolved
and you're overdue.

SLA extension cover basic situations and there are a lot of space for
new options to cover more complex scenarios, but every new option
requires a lot thinking and increases complexity.
