What do you propose "grep" do with the infinite number of metadata items
that "data" could have associated with it?

Your answer had better be "nothing" since it cannot be programmed to deal
with all possible permutations of all the possible metadata items that
might come and go.

What you are suggesting is making something that should be application
specific hard wired into the kernel.  Every application can't know what
to do with every kind of file.  Even operating systems, such as VM/CMS
which supports file attributes, don't get it right.  Programs that only
take LRELC=60 text files don't know what to do with an LRECL=80 text
file.  What makes you think UNIX could ever get it right?
