Of course.  It's not about writing the target in the first
place, it's about reading it and maintaining it later.  Say,
a year from now, someone adds a new method but doesn't spend
all the effort necessary to make all N targets work
correctly with the change, which is reasonable since it's
not sensible to insist that everyone be familiar with the
issues of all N targets before doing any work.

Absence of an initializer is a simple indication that
someone should look at it and make sure it's ok.  Putting in
a zero initializer is an easy sign for, "yes, this is ok".

"Always initialize all members and methods" is a simple
style rule that encourages good programming discipline in a
couple ways, and if I were in charge I'd be adding all the
missing zero initializers rather than taking away the
existing ones :)

I'm not sure why you call it "an awkward style issue".  If a
block of initializers seems long, it's because an interface
is complicated, and glossing over that by making the
initialization look simpler is counter-productive.  The
correct point to attack is the interface itself, not the
places it's used.
