If you think it through, a test use flag still is needed in the cases
where the rdep itself would change if test was enabled; such a source
is fairy rare, but not always just someone being moronic- certain
cases to do testing, the tests need to reach in fairly deeply and
recompilation for compile vs test isn't exposed.

It's not FUD; it's rendered deps, and a demonstration of how they
collapse down naturally on their own regardless of how you generate
them.
Quite frankly, it's a fairly effective demonstration in my views, but
so it goes.

becomes the following under the proposal:
"""

app-arch/xz-utils"
dep:build? ( virtual/pkgconfig )"

Suspect I may add that to the doc; it's a good example of the ground
level simple gains for devs inherent in the proposal- thanks for
helping improve it.

I think I'll take the risk, and assume people capable of discussing
DEPENDENCIES and vaguely knowledgable in the ebuild format will be
able to understand how their ebuilds will change; thus I'll skip that
request of yours.
A productive suggestion for you; you should go looking through the
tree finding cases where DEPENENCIES is a regression in form at the
shell level, or rendered deps level.
Should you manage to find something that's not contrived or
intentionally cracktastic, I expect people would be interested.
