I don't hack on DMD much, but here's my take on the matter: Asserting every function parameter (where applicable of course) is good practice because it helps you catch bugs as early as possible. If you don't do this, you could end up with null pointers far into the program where you then have to spend time figuring out where it came from. This is especially nasty when e.g. building tree-like data structures and you can't just look at the call stack to figure out where you got a null pointer from.
That is true for some programs. It isn't true for dmd, where tracking down the source of a null pointer has never been particularly difficult.
There are a lot of refactoring things that dmd would benefit from. Adding assert(p!=NULL) everywhere will not add much value.
