I am not sure I agree. This means one could accidentally override make
variables. Being explicit as in the original version is more deterministic.
Otherwise somebody would have to audit each recipe's makefile once a
variable is added or removed from the bitbake environment. That doesn't
scale. It would appear that the -e flag was removed from EXTRA_OEMAKE in rev
aeb653861a0ec39ea7a014c0622980edcbf653fa for a similar reason... Even the
make manual recommends against using -e.
