In general that email is correct, changes to the variables won't
propergate between tasks.

There is an exception in the do_package -> do_package_write_xxx
process. These use emit_pkgdata() to save the data and
read_subpackage_metadata() to read the data back in.

Not all variables are covered, but the ones you mention above are. As
long as you modify them somewhere during do_package such as adding a
function to PACKAGESPLITFUNCS, the changes will persist in the
packaging.

See above, I believe you can change these values and other recipes do
this as long as its somewhere within the do_package task.
