There's also another issue with  --sym - which is that, as described, I 
think you are assuming this semantics:

* if no --sym is specified on the command line, do whatever jextract 
does today
* if one (or more) --sym is specified, then switch into a mode which 
means "only these please!"

I have a feeling that, maybe, we are trying to conflate too much in a 
single option? That said I see the simplicity appeal.
