I haven't had time let to look at the webrev yet but on the CLI options 
then I think the above approach looks quite good. There are 3 existing 
plugins that expose --exclude-XXX options so you might want consider 
renaming "omit" to "exclude" to be consistent. Another suggestion is 
consider adding the "-files" suffix to the debuginfo values so that it's 
clear to anyone reading a script that it's about exclude or keeping 
debuginfo files, e.g.

--strip-native-debug-symbols exclude-debuginfo-files
--strip-native-debug-symbols keep-debuginfo-files=pdb
