I don't care about validation either but a good and important effect it has is 
that we can use SimpleXML features like XPath for future PHP5 extensions when 
dealing with Flexform XML. An example from my testcase:

$flexform = simplexml_load_string ($testPageRecord['tx_templavoila_flex']);
$xpathRes = 
$flexform->xpath("//data/sheet[@index='sDEF']/language[@index='lDEF']/field[@index='field_content']/vDEF");

see above. Validation is not neccessary and a schema (I'd prefer Relax-NG) 
would be a bonus feature. But still well-formed XML has advantages in other 
areas, too.

As mentioned, only extensions which access the XML directly are affected. For 
example the extension "eu_tradvoila" won't work anymore - but that's no 
problem because it was a bit of a hack and the functionality is included in 
TV 0.6.0 anyway.

Let's take the risk of breaking someone's extension and go the full flavoured 
way. Then we're done with it ... for now.
