Well, now I'm coming to believe you're just making a mountain out of an
anthill.
1. First of all, according to a post I saw from K1JT ..... "since June
15, 1983 FCC does NOT require US amateurs to use a CWID with data
modes." I haven't found the FCC statement that confirms that, but at
least for now I'll take his word for it. Out of the millions upon
millions of digital QSOs involving hams from the U.S. and other
countries I've never heard of anyone getting in trouble for not IDing
with CW. Have you?
2. Secondly, we don't want people sending CW IDs in FT8 at all because
it just trashes subsequent transmissions on that same frequency. Those
CW tones you want to send are worse QRM than other FT8 signals.
3. If it's WSPR you're worried about, why is anyone bothering to use
special callsigns for non-contact purposes?? It's purely a propagation
indicator where nobody gives a rats butt about special callsigns, and
I'd bet that almost anyone with a really weird special callsign also has
a legal, more conventional callsign they could use for WSPR. Please
describe a realistic situation where that wouldn't be the case if you
disagree.

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 withITU Radio Regulations
<https://life.itu.int/radioclub/rr/art19.pdf#page=7> (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.
