Configuration options only apply to the local aspects of the repository. 
That is, when you clone a repository, you don't get the configuration 
options from it, in general. And changing configuration options on a 
repository does not have any effect on the content it contains. So 
configuration options aren't appropriate.

Git doesn't have any way to represent owners or groups, and they would 
need to be represented carefully in order to make sense across multiple 
computers. If you're adding support for metadata-as-content (for more than 
"is this a script?"), you should be able to cover all of the common cases 
of extended stuff, like AFS-style ACLs. And if you want to allow 
meaningful development with this mechanism (as opposed to just archival of 
a sequence of states of a live system), the normal case will be that the 
metadata beyond +x is manipulated by ordinary users in some way other than 
modifying their working directory. So the normal case here will be like 
working on a filesystem that doesn't support symlinks or an executable bit 
when this is important content.
