Well, i'm also not sure why kern values should change. :-) But i just
compared kerns used in cmti10.pl and cmu10.pl, and they appeared
rather different: in cmu10, kerns (positive) are more then twice
smaller. Negative kerns are comparable, but are a bit bigger (in
absolute value) in cmu10.

Am i right that glyphs in cmu10 are very well approximated by
unslanting cmti10 by -0.250?

I just was trying to produce a faked unslanted italic cyrillic virtual
font from cmu10+(wncyi10 slanted by -0.250), and noticed that kerns in
cyrillic part remained the same as in italic font (wncyi10), but in
latin part (cmu10) kerns are not the same as in italic font (cmti10).
