Yes, that only *seems* to be so.

Your logic is flawed.  You simply cannot know about *all* browsers.

AISB, *some* browsers, perhaps the majority in terms of market share, do not 
implement the SGML Declaration for HTML 4.01 [1] properly, which specifies 
the SHORTTAG syntax for HTML so that `<br />' is equivalent to `<br>&gt;' in 
HTML (that allows, for example `<h1/My Title/' instead of `<h1>My 
Title</h1>') [2].  But the W3C Validator [3] does, which is why, e. g.,

  <link … rel="…" … />

is _not_ a Valid HTML 4.01 fragment (as `&gt;' would be character data which 
is not allowed within the `HEAD' element).

This has led to the *current* HTML5 Working Draft regarding the trailing `/' 
between `<' and the corresponding `>' of a start tag as allowed and optional 
in the HTML syntax of HTML5 [4,5].  But you SHOULD NOT rely on that
outside of HTML5, perhaps not even in HTML5 until it has become stable.
