I would like to enable tree-like exploration.
In other words, it would be cool if the returned options could contain
new "explorer".

So the supplier basic cycle would be like "while
(options.stillHasExplorer()) {  nextOptions =
options.getExplorer().apply(options); }"

1. Not that serious.
2. Testing "different jar versions", "different java versions" happens
more often that once a year.
3. 5 minute convenience multiplies by the number of usages and powers
up to the number of copy-paste errors.
