Most users expect the data to be expanded by default. Most call sites
also use getVar(xxx, True), its uncommon to see expand=False, outside
the core of bitbake.

So the ultimate advantage is a more sensible default which is what the
user expects and leads to neater/smaller code.

We have had several bugs requesting this and it does confuse people.

I have heard regrets from some of the original developers that the
default wasn't True as well.

Cheers,

Richard
