Comment 4 for bug 227532

I think the motivation for the change (setting mediatype to texts early in the process)
is that there are some operations you cannot perform if you don't have both
a mediatype and a collection set. For example, doing bookops from metamgr
requires both mediatype and collection to be set for the bookop to be launched.

If there's a problem with the work-in-progress being too visible, maybe we could
do something like set the mediatype to pre_texts, and maybe have the details
page have some disclaimer on it that the material is still being developed.
(Don't know how hard or easy that might be.)

In any event, luckily somebody apparently has already implemented Raj's
suggestion of setting noindex=true early in the process (it was already in
the code right where we currently set mediatype to texts).
