It is important to recognize that those user agents were

a) designed according to the HTML specification of their day.

b) in MASSIVE distribution. We're not talking about just Netscape and
Microsoft, but Lynx, Lycos and everything in between.

Even if all of the browsers were updated to support arbitrary GI's and CSS,
we have only solved part of the problem. If I invent a new GI that I call
"MyLink", how does a browser know to interpret that as if it were an <A> or
<LINK>? We need a subclassing mechanism. Hopefully the SGML working group
will allow this through architectural forms and DTDs. But in the meantime,
we must stick with:


so that the semantics of the new element can be inferred.

The former is compatible with the existing user agent base (and thus
preferable). The latter is not.
