Yes, I've said that many times.  Glad it's finally
sunk in.  That's a sufficient reason that it should
not have been used in things like the bookmark list.
(Even adding it to buffer-menu was a mistake.)

A more important weakness of t-l-mode is that it
doesn't support arbitrary sort functions - it
doesn't make it easy to sort other than by an
individual column.

To me, t-l-mode is too limited for most real,
useful uses of "tabular" data.  It should never
have been imposed on the bookmark list (I don't
use it in Bookmark+).  And it's useless for
things like Dired (thank goodness).  Maybe the
same for Ibuffer; dunno.
