shouldn't that be made "obsolete" rather than "reserved"?

My first choice would be to not say anything about bit 0 in this
paragraph -- delete FLAG from the list as you say, but do not add the new
sentence.  Leave it defined as "obsolete" in Table 12, with no other mention
anywhere in the document.

But if you are going to say something about it, don't use the name, as that
is obsolete and every definition of it and reference to it is being removed
(per your other changes).  For example, say "Use of bit 0 is obsolete in
SAM-2".
