That is a direct quote from ISO and will continue to be true until it is not:
Status Proceed 40.99 Full report circulated: DIS approved for registration as 
FDIS - awaiting Approval Registration 50.00 Final text received or FDIS 
registered for formal approval - expected to take about 6 more months perhaps, 
based on 9899 C timeline 2024-05-05..2024-10-31?

I await making the change final (or dropping it), without holding my breath:
I see Austin Group Bugs & ML & JTC 1/SC 22 feeds.
Even IEEE got on board with minimal editorializing.
ISO has a lot of editorial rules to meet - they seem to have standardized the 
requirements for standards committees - I wonder if that has an ISO number ;^>

Not really, so I too was disappointed, but they want to see widespread support 
before committing, and perhaps some were not likely to agree?
