I don't know if this was intentional or not but it appears that the UCP and legacy editor preferences are linked. Some additional notes about 2010 Editor is that, when selected as the preferred editor, users can switch between it and 2017 Editor (visual). When switching from 2010 Editor to 2017 Editor (visual), the URL doesn't change at all. However, when switching from 2017 Editor (visual) to 2010 Editor, "veswitched=1&oldid=revid" where "revid" is the revision ID gets appended to the query string. Also, if you select the 2010 Editor but uncheck "Enable the editing toolbar", then you will get a layout effectively identical to the 2010 Editor but without the top toolbar. 2017 Editor (visual) will still have its toolbar if you switch to it.
