Probably a good idea, since it would offer an opportunity to point out 
that Italic Correction has to be specific both to the typeface and to 
the individual character in that typeface.  It doesn't make sense 
otherwise.  It isn't even accessible as a \fontdimen, because there is 
no assurance that it will be exactly the same for all characters in the 
font.

By the way, I wish DEK had included two more \fontdimens as part of the 
usual set for regular book fonts.  I have to add the equivalent of 
Adobe's ascender height and descender depth as additional \fontdimens to 
any font I regularly use.  That is the only way to ensure that the 
\strut is proportional to the specific font, with \strutheight and 
\strutdepth available for line spacing adjustments in whatever leading 
is in use.  Quite important for insertions of CJK characters, etc.,  in 
a line of Roman type.
