Comment (by ryanduff):

 Did some more digging. Not tied to inactive widgets, but rather
 unregistered widgets. Core adds a few widgets to the sidebar on install
 which gets them an entry in the DB. _register_widgets() then excludes them
 from the _register() call which is what is triggering the get_option() as
 noted in the backtrace (image in [comment:3 ryanduff]).

 So... on a clean install if no widgets were added to a sidebar, you'd
 actually be adding about 12 db queries, not including whatever the current
 theme is registering.

 This looks to be any widget that has never been added to a sidebar, so the
 number of queries will vary from site to site.

 I'm still trying to grok the WP_Widget class internals, but it looks like
 it may only need to do this if the widget is actually registered in a
 sidebar and not global, at least on the front end. If you're in admin or
 customizer, it still needs to instantiate the widget from the looks of
 things.
