Is there any resource you can point me to where it explains more
carefully why and when this has changed?

PMS
5.2.4 make.defaults
"Variables to the right of the equals sign in the form ${foo} or $foo are recognised and expanded
from variables previously set in this or earlier make.defaults files."
5.3.1 Incremental Variables
"Incremental variables must stack between parent and child profiles in the following manner:
Beginning with the highest parent profile, tokenise the variable’s value based on whitespace and
concatenate the lists. Then, for any token T beginning with a hyphen, remove it and any previous
tokens whose value is equal to T with the hyphen removed, or, if T is equal to -*, remove all
previous values. Note that because of this treatment, the order of tokens in the final result is
arbitrary, not necessarily related to the order of tokens in any given profile. The following
variables must be treated in this fashion: 
  • USE 
  • USE_EXPAND 
  • USE_EXPAND_HIDDEN 
  • CONFIG_PROTECT 
  • CONFIG_PROTECT_MASK"

Ok, I clearly had missed that.  A long time ago I think we needed it in
order to have USE-flags retained.

Thanks
