Note that all the issue reporting templates recommend doing that not just for stability issues or long loading times, but for any problem you report. And the poll on the official feedback posts for all updates the second question (which is not gated on any issue reporting) is something to the effect of “did your remember to clear your community folder?”
It’s pretty easy to get the very strong impression that this is what you’re meant to do. If Asobo does not in fact recommend this because it doesn’t properly update the simulator state when you do it, then they should maybe change their communications.
