Btw, this is actually the _only_ kern pair for digits in
this font (Palatino Roman).

Because I use to remove such annoying kerning pairs when
installing fonts for TeX :-)

As far as Palatino is concerned, I admit that "11" looks
indeed slightly better with a small amount of negative
kerning.  OTOH, this ruins tabular arrangements, which
would a far more serious drawback.  Note, however, that
I would not remove such kerning pairs, when digits have
non-uniform width.

You did not examine the fontinst sources of PSNFSS
collection, see <CTAN:fonts/psfonts/psnfss-source/>.
