As I wrote about six months ago, this is not the complete
story. Yes, there are a few GVP accelerators in the field
that do not support non-word-aligned writes of longwords,
but fixing this is as simple as changing a PAL (U50). And
all current boards _do_ support this feature (in fact, I've
just tested it on mine).
