I disagree with the code deletion. It makes it harder to combine various
d-i components across distributions to support as many use cases as
possible. Keeping a few old lines of shell code shouldn't be a problem.

I started using this successfully but then I stumbled upon issues with
WPA2 (which turned out to be missing modules as we now know), and got
to publish Jessie Beta 2. So the current logging situation might not be
ideal yet but it seems sufficient to vastly improve the current state
of affairs.
