I don't know exactly how defconfigs are handled, but I can imagine that
the responsible developer is running "make oldconfig" on the system in
question from times to times and copying the result back to the
defconfig file. The purpose of updating defconfig files is to make
configuration option renames transparent.

I can't see why defconfigs which select the option on question are
different from defconfigs not selecting it in this respect. In both
cases, if we don't update the file, a subsequent "make oldconfig" will
ask about the "new" option.

Or is there a specific procedure to update defconfig files which
answers "no" to all questions by default?

I have done so, sorry for the trouble.
