   We can enable cache always but the problem with that is that sometimes the performance actually degrades instead of becoming better. It should be left to the developer to decide if he/she wants to enable it or not. Another thing is, if someone wants to monitor the performance of the cache, example: hit/miss counts, they would enable the cache and look at those registers, so, keeping it conditional is better.
