Well, it is not really easier, since there is no easy way to comment on the code. Also, transparency is lost.

The code looks clearer, but there are still two more or less identical structures in there.

Given everything that happens within a hid packet, this really, really does not matter much.

Rushing things will only cause us grief further down the road.
