Why not just call save() yourself?  save.image() is a rarely used 
(directly) convenience wrapper.

And why do you want to change the compression level?  There is very 
little advantage in using it for 'gzip' compression, and really the 
only significant use is reduce it to save time for xz compression.

If you are volunteering others to add a feature, it behooves you to 
explain why it would be useful to you and might be to others.  Nothing 
is 'disabled': this is a new feature request ....
