Or a counter, of course, rather than just the marker.  From the point
of view of implementation in a database, I think these two options are
approximately the same, so I prefer the counter because it provides an
additional bit of data (that is, that the domain is changing -- you
can watch it happen).

Well, no, that's part of the point of the new proposal: the registry
_doesn't_ have to figure that out, because the counter can be set to
"unknown" (in a SQL database, you'd probably use NULL).  To support
this feature, however, the registry would have to track deletions of
domain names in the future.  So it wouldn't be free, but it also
wouldn't be hard to implement.  (Any real SQL database, for instance,
could do this with an ON DELETE trigger.)

Best regards,
