With v18beta1 already out in the wild, I think that we are too late
for taking any action on this version at this stage. Putting a
deprecation notice for a selected set of conversions and/or encodings
and do the actual removal work when v20 opens up around July 2026
would sound like a better timing here, if the overall consensus goes
in this direction, of course.
