This ensures a rebuild does really build from scratch when ccache is in use.

I was wondering the same thing, with the default configuration:

bitbake.conf:# Assign CCACHE_DIR a default value to fix a bug of ccache 3.1.7,
bitbake.conf:# since it would always create CCACHE_DIR/.ccache even if
bitbake.conf:export CCACHE_DIR ??= "${@os.getenv('HOME')}"

Our default CCACHE_DIR defined above this has ${PN} in it so just the
package you are cleaning.

I'm worried about what happens if someone changes the CCACHE_DIR to a single 
shared location.

That line is only in the class file and that class redefines CCACHE_DIR
to include PN.

It would wipe that shared location upon a clean unless they change the
