The volume of changes to the config that this will require, a minor memory 
usage increase (I suspect), but more importantly it increases the complexity 
for the end user. Right now ??= is used sparingly.

Wouldn't it be the reverse at the moment? We do add new things to the poky 
distro config when we need to test them and those new things might not be 
desirable in your configuration.

Distro configs should remain fairly static once initially set. FWIW, we do call 
out any needed changes between releases in the migration information within 
the documentation.

Cheers,
Paul
