Sparks in 3.0 and/or migration?

What would I migrate a spark too, a library?

As far as I can tell, in most cases sparks is used to distribute libraries, so yes, though they can also include helpers, models, and config files.

...and in most cases it would probably be better to use code available via Composer, if you can use it in your environment, as @solidcodes suggests, though there is no optimization in CodeIgniter for either Sparks or Composer, and there are limitations in both cases.
