So ... here is my suggestion:
In "Admin" > "Maintenance" > "Forum maintenance..." > "Topics" we have a "category" to "Move topics" from a board to another, would be nice if we will have a check-box "Move sticky topics", by default it will be enabled, no more explanation needed, you know what it should do.
Could be useful when we want to reset a board, some requests, but not the models/rules also.
Thanks :)
This is something that should have been in SMF a long time ago and I've added it to 2.1's tracker under https://github.com/SimpleMachines/SMF2.1/issues/853 to be included.
