Yes, that's traditionally called LATEST, and Gforth has it, too.
However, the DEA/nt/NFA is not a standard concept, so you can do
nothing with that in standard programs.  And there is very little
chance of it being standardized (not for technical reasons).

In any case, neither of these words is a replacement for the other,
because

1) There are words with an xt that do not necessarily have a
DEA/nt/NFA (unnamed words), so LATEST cannot be used to build
LATESTXT.

2) On some systems (including Gforth) there is no reliable way to get
from the xt to the DEA/nt/NFA, so LATESTXT cannot be used to build
LATEST.
