bitbake manual, chapter 3, examples of conditional syntax:

https://docs.yoctoproject.org/bitbake/bitbake-user-manual/bitbake-user-manual-metadata.html#examples

correctly distinguishes between A_foo_append and A_append_foo, but how
often would one use that first form, anyway?

most uses of conditional appending are either just straight
appending:

VAR_append = "fubar"

or used with an override thusly:

VAR_append_x86 = "snafu"

is there an actual practical usage of, say:

VAR_x86_append = "huh"

i can't remember the last time i saw something of that form and,
while it might be worth explaining, it seems that the reader might be
warned that that form is almost certainly *not* what they want.

thoughts?
