Huh ! There are various film developers in common sizes for
amateurs like us !
Xtol, D-76 and HC-110 among others ...
And for Xtol, I checked B&H and Adorama websites and I don't
see any other package other those that are discontinued (5
and 50 liters), does it mean Xtol is completely gone ???
As, and except some Ryuji's formulas, there are no real
replacement for it, this means stocking, stocking, stocking
...
Or, can we ask Kodak to publish a formula for a reasonable
replacement ?

I don't know for certain what Kodak is discontinuing and
what they will continue to make. The only notice I've seen
so far is the one from Photographer's Formulary unless
someone has seen something on the Kodak site. I looked a
couple of weeks ago when I got the news letter from FF but
could not find any substantiation.
The chemicals not mentioned in the letter were liquid
concentrates such as T-Max and the print developer. Its hard
to believe that Kodak does not sell enough of this stuff to
justify continuing making it. If not really clever
management would find a way to farm it out. Maybe, after all
the propaganda about Kodak continuing to support film it
will all turn out to be rubbish.
There are a number of patents that tell how to make some
of the familiar chemicals, like Kodak Hypo Clearing Agent,
all sorts of fixers, buffered D-76, etc. Kodak's versions of
these familar items are not quite the same as published
formula, where they exist, because Kodak adds sequestering
agents and other stuff and uses special versions of some of
the chemicals, for instance to allow packaging everything in
one container.
If Kodak stops making chemicals can film be far behind?
The problem is that Kodak has a great deal of sophisticated
knowledge which is not shared so probably no one will be
able to exactly duplicate what they do. Especially true of
film.
