The first is collisions. If you have to networks on one collision
domain, it is potentially very noisy.
The second is security. You have none at all this way. At least with a

As to your case, sticking a second IP on WAN so you can log into a DSL
box is not a big issue. But if you make it easy to be sloppy, then
people will do it in cases where it is a problem, and then we get the
support questions. :)
