You need to seperate Compression and Caching here.

Compression does not reduce CPU Load, Caching does.

There are Many *good* caching plugins for WordPress, But none of them can  
deal with a often changing Dynamic website AFAIK, And none of them belong  
in core in my opinion as they're better suited to running as plugins.

WordPress removed Compression in 2.5 as it was a buggy function, It didnt  
work on some servers due to double-compression, and some users couldnt  
understand that. In addition, It didnt do caching, so it would increase  
server load and subsequently, load times.
