Now you know why we have been using Doxygen as GCI tasks for years.
More people should mentor GCI to do this type of random, broad clean up.

This is OK as a default but it shouldn't be the only option. I wouldn't
a comment that was more specific or use that when a more specific
comment is better.
We don't want comments to exist just to improve a comments to code ratio.
They are supposed to be meaningful. IMO the copybrief adds no value to
the file when reading it. It only adds value when the file is processed and
you are reading the Doxygen output. So use this as a default but don't
delete @brief's which are better and this does not stop someone from
writing a more meaningful brief.
I still don't know where in the output, text beyond the @brief on a file
block goes. Any ideas?
