IMNSHO within reason, compile times are not an issue. The longest compile 
time I've seen with DMD (dparse processing the full D grammar so I don't 
expect to see it go much higher) was 14min. That's about par for finding 
bugs. I'm willing to run with longer compile times if it generates faster 
or more bug free code.

The only reason I'll back a change in meta land would be to make more robust, 
readable or capable code.
