If we make the paths compatible, they are more complicated. So,
we have the choice between an incompatible break to a clean and easy
thing (i.e. only search "new") and another incompatible thing which is
complicated to debug (search "new" and "old").

Really, even if we try to search "old" and "new" locations, we
cannot guarantee that the same files are found than before the

Consider this: someone with a TL 7 installation upgrades to TL 2004. He
reuses his texmf-var tree where he has a psfonts.map file in old. We
have to search "new" before "old", otherwise a new psfonts.map generated
by updmap will not be found.  On the other hand, the user might expect
his modified lucida.map file in his local texmf tree to be found before
the version that TL 2004 distributes in the main tree, but this is no
longer true (because the distributed file exists in new which has higher
precedence than his file in old; even though it resides in a texmf tree
with higher priority).

No, just one more year of confusion.
