I thought so.

"OO" and "OOO" are special escape codes to indicate a switch to a
different coding system.  We don't have to worry about them in the
registry because they are not assigned in ISO 3166, and because
draft-registry defines only one "coding system," with a choice of
registered or private-use subtags.

As described in a draft update to ISO 3166-1:

"8.1.4 Extended facility of user-assigned code elements (escape code
element)

"If the number of user-assigned code elements in 8.1.3 is not sufficient
to cover a particular user requirement, the alphabetic code elements OO
or OOO or the numeric code element 000 are to be utilized to indicate
that code elements other than those defined in this part of ISO 3166 are
used."

Or as paraphrased by Clive Feather:

"The codes OO, OOO, and 000 are designated for use as "escape codes" to
indicate that additional codes are being used."

I can't find any previous message about this in my "Sent" box.
