On comp.tex.latex there was some discussion w.r.t. document layout
stability and hyphenation patterns:
Subject: Consistency of US hyphenation patterns across distributions

Up to today, noone has ever mentioned a similar problem here, and I
must admit that I've never thought about it.
The current state of groff is simple: It does *not* assure layout
stability, this is, it is quite possible that documents look different
if processed with different groff versions. I don't think this is a
serious problem because you can always use an older groff release in
case this stability is important to you.
