No, it wasn't. The default definition of \ligature (which will be in effect
the first time the line below is executed) is the same now as it has always
been: \gobble_three.

Hence the effect of this line has always been to make \wnlig a noop.

This works, because the definition of \Ligature (which is new in the recent
fontinst) is to expand to \ligature, which is what \wnlig was supposed to
do. It is however better to do

  \setcommand\wnlig{\ligature}

or more verbosely

  \setcommand\wnlig#1#2#3{\ligature{#1}{#2}{#3}}

since these follow the pattern of \lc, \uc, \lclig etc.
