In reply to AJ.

The first thing that crossed my mind was exactly as what you've pointed out. I kept seeing wp-rocket popping out from time to time with bloggers reviewing it, but I still fail to see what is the selling point. I can indeed use 3 plugins if i must, and search online for a solution if i bumped into it. Plus the dev at autoptimize is pretty responsive while even offering it for free.

Regarding the dns-prefetching, I'd say that is a misused feature for the in-experienced. I have related post at every post, and some have more. The prefetch will load every single page and cause a really slow start.

Like what you said, one thing that was missing that would be great is the inline and defer css, which would be a killer to this plugin. I myself, although inexperienced have tried with the inline and defer using autoptimize, with very little success, mainly because my homepage and post page are all different (which after I found it out, have to revert everything back to render blocking css).

If you were me (referring to the plugin dev), I'd take feature request here as a plus sign. Alot of business fail down the road because they ignore things like these and chose to think with their own and do their own things. Now, you even have free feedback, which some business don't even have the privilege. Saying "So, if you have a problem, you are alone" is not a very wise choice of words.
