[tex-live] Latin Modern bug in lm-texnansi-os.enc

On the ConTeXT mailing list, Idris posted some messages because he was
trying to use oldstyle numerals in the latest Latin Modern release,
and was experiencing two pretty big problems:
* really bad kerning around the oldstyle numerals
* pdftex generated errors for the typewriter fonts, complaining
"glyph `one.oldstyle' undefined" etc.
The implementation of 'automatic' oldstyle numbers in ConTeXt uses a
set of encoding files that used to ship with LM (lm-xxxxxx-os.enc).
By way of a map file fragment, this allows to switch the fonts
'en masse' from lining to oldstyle (and back) without the need for
special metric files, which is a pretty nice feature.
Those encoding files now apparently obsolete: they still refer to
glyphs named e.g. `one.oldstyle', whereas in the current release of
the LM fonts it really should be `one.taboldstyle'.
While writing a bug report, I noticed that these encoding files are no
longer in the font distribution (They are still included on texlive2007,
but I don't know if anybody except ConTeXt attempts to use them).
Is this trick to get oldstyle now officially unsupported? That would
be a shame, because there are no oldstyle-using TFM files in the LM
distribution either ...
