 From #31611:

 >Avoid configuration types where NULL and "" mean different things. We
 would have to add a new routerset type meaning "all routers", (maybe,
 "*"?) and have that be the default for EntryNodes. [We probably could not
 make NULL mean the same as "" for all cases, since there are lots of
 string-valued configuration types.]
