New 2020 Setup Wizard Step 5 - Opt out of picking a theme
With the new 2020 Setup Wizard, Step 5 has a "Pick a Theme" area with no option to opt out. For existing theme installations, it is unnecessary and although in most situations might be fine if you switch, may not be for all and cause problems. The assumption on this set is you are a brand new site, established sites would not want this possible disruptive step.
You are able to continue using your existing theme which is similar to skipping. Let us know if you think we could make that more clear!
