E pur si muove
UTC may no longer serve as a kind of solar time (after 2026 or 2035, or
somebody said 2040 the other day), but civil time will continue to have
engineering requirements tracing to both solar and atomic time scales.
Shenanigans will result, bedeviling future blinkered technocrats.

Resolution 655 was approved by the WRC plenary, reportedly in a
very routine manner and with with neither drama nor long speeches.
The full text of the resolution is on page 399 of the provisional final acts:

My Tl;dr version of the resolution is:
Timescales are not spectrum regulation, we defer to CPGM
and BIPM on that, but will handle any fall-out as far as
radio signals go. Please keep DUT1 less than 100 seconds.
Then BIPM then issued this press release:
https://www.bipm.org/en/-/2023-12-12-wrc-dubai
Which I read as death notice for the leap-second, with further
details of the funeral to announced after CPGM's meeting in 2026.
