[wp-hackers] Minify Scripts and CSS and why it isn't completely possible

[Jacob Santos]

With WP Speedy and my plugin, I'm noticing that not all plugins are 
using the Script and Styles API. This prevents those stylesheets and 
scripts from being minified. I plan on going through the plugins I have 
and "fixing" them, and hopefully the patch is included for the future 
versions.

Why don't more plugin and theme authors use the Scripts and Styles API? 
Is it a documentation issue or is it not high enough of a concern?
