I never considered TUS as the ultimate truth in the matter of Indic scripts,
but accepting this...

Of course, if font designers ONLY base thir work on TUS, the result is
unlikely to be of ultimate quality.
However, I do no believe this is common behaviour.

Please elaborate, I do not see the point here.

Either the font is correct, and the problem does not show up, which is BTW
my relation of the case you mentionned; in fact, for Gurmukhi I know quite
well, every version of Uniscribe I know of, starting with the first beta I
saw in 1998, deals correctly with Gurmukhi sihari, provided you use it with
a properly encoded font (and early betas did have a different scheme for the
features, also available with plain IE5).
Or the fonts is plain incorrect. Correct placement of the I matra is a very
basic mandatory feature.
