I'm in agreement on obsoleting "client" as well. On the pace of change,
I'll defer to you. I was trying to elicit a recommendation on future use
of "client" when I asked:

===
What's the combined effect of this documentation update in terms of the
recommendation for switching over the Linux kernel? Are we to use
controller/client or controller/target?
===

"Synonyms" from patch 6 does say that controller/target is preferred but
couched it in the caveat "If speaking about I2C in general" and
adapter/client when "discuss[ing] implementation details." I was trying
to give space for an unambiguous recommendation.

I think we are on the same page here if we just remove the caveats.

Thanks,
Easwar
