Hi Richard,
I don't think this is a recent regression. What I can say is that
bb.data.update_data (or whatever this method was called) is a
relative cheap operation. So technically there would be nothing
preventing us from adding it.
I'm certain that we will see funny/unexpected things with the OE
metadata when calling update_data on immediate assignments, so if you/
we decide to do it I would propose the following strategy.
Use the existing bitbake and pickle/dump each parsed file, then use
the new bitbake and pickle/dump each parsed file as well. Then run a
small algorithm (I think I have comitted it to bb.data) to diff two
smart_data dictionaries.
I think it is fine to change that, specially as update_data is quite
cheap nowadays, but I would like to see the difference in our metadata.
