I was not sure, that why I began this thread. I started with latex example,
then strip it down to plain tex one and after that came to context
minimal example.
AFAIU, context suite doesn't have "plain" pdftex and luatex formats,
therefore I compile minimal plain tex example with TeX Live 2011, and
luatex doesn't print such message though it reads vf file.
The problem indeed may be it luatex and how it works with vf fonts, but
as I said, I'm not sure (don't know very well either plain tex or context).
P.S. Unrelated: seems I completely lost, I read web sources, the
quoted extract from luatex source and I don't understand how this
number '32212676346' can be presented as
cs.b0 * 256 * 256 * 256 + cs.b1 * 256 * 256 + cs.b2 * 256 + cs.b3
If I don't lose my math skills the '32212676346' is
32212676346=7·256^{4}+128·256^{3}+6·256^{2}+110·256^{1}+250·256^{0}
