Over the development of yii meanings of sending 0 or -1 as duration to cache components have varied. Though its not difficult to remember these mappings but some sort of constants would appeal more, specially in terms of code readability to a new developer, that is:

$this->beginCache($id, array('duration' => CCache::DISABLE));

is better than:

$this->beginCache($id, array('duration' => 0));

Few of the constants that i could think are:

• DISABLE (same as 0)
  
• PURGE_DISABLE (same as -1)
  
• FOREVER (same as specifying a month or 2, this could actually depending on cache component like for APC it could be 7 days, for file it could be a month)

Agree. I think it can be done in 1.1 in case of cache but it's definitely the style we'll follow for Yii2.
