CWID is not required in the USA. Why waste the bandwidth? It will just be more
background noise in our ever crowded sliver of digital frequencies.

Hi friends,
Just to clarify, the issue is not the identification interval... rather, the
issue is whether it is possible to identify at all.
A callsign such as XX0YYYY is compliant with ITU Radio Regulations (Article 19,
19.68), but as far as I can figure out it's not possible to identify with a
callsign of that form using WSJT-X and WSPR (and I think it isn't possible to
identify with any of the modes -- not even with the CW ID feature).
Note that ITU regulations explicitly provide for up to four characters after
the digit, and it is only the last character which must be a letter. For
example, the callsigns K7123X, K7ABCD, and K722AX are all valid callsigns
according to the ITU regulations.
Furthermore, even longer callsigns are authorized Article 19 at 19.68A. ("On
special occasions, for temporary use, administrations may authorize use of call
signs with more than the four characters referred to in No. 19.68.") An example
would be K7VERYLONGCALLSIGN -- perfectly compliant with ITU rules "on special
occasions for temporary use".
In some jurisdictions under some circumstances a license requires a fraction
bar and additional characters after the callsign.
In the U.S. -- and likely everywhere else -- national identification
requirements can met by the transmission of the callsign in CW using
International Morse Code. Notwithstanding any limitations in the 28-bit digital
encoding scheme used for WSJT-X digital modes, a free-form CW ID callsign field
would empower all users to perform their station identification duties --
something that is not currently possible with WSJT-X for some callsigns.
