How to complete t/README file?

How to complete family numbering in t/README? Curently we have:

-- >8 --
First digit tells the family:

        0 - the absolute basics and global stuff
        1 - the basic commands concerning database
        2 - the basic commands concerning the working tree
        3 - the other basic commands (e.g. ls-files)
        4 - the diff commands
        5 - the pull and exporting commands
        6 - the revision tree commands (even e.g. merge-base)
        7 - the porcelainish commands concerning the working tree
-- >8 --

But there are tests which have 8 or 9 as first digit:

	8 - annotate, blame, pickaxe
	9 - send-email, git-svn

8 seems to be porcelanish "archeology" (analysis, interrogators) 
commands, 9 seems to be interfaces (to email, to svn). Do you have idea 
how to name those families?

P.S. Do I understand correctly that gotweb tests would eblong 
to familiy 9 of tests?
