The simplest answer to "why", I think, is "because that's how SGML
types are".
In other words, it's far less complicated to follow this rule in
(X)HTML than understanding its origin.

A user-agent may not be able to understand the id (thus ignoring it).
Potential results: can't follow a link to a particular position, can't
apply style...
I guess that affects accessibility.
