Comment (by celloexpressions):

 As with any customizer section, the CSS section cannot assume that there
 are no non-core controls added. We definitely need to only auto-size to
 the full size when the core control is the only one in the section; and
 even then, I'm not sure that showing a larger textarea provides usability
 benefits. The area auto-resizes based on its contents (at least, last time
 I checked), and an overly large input may imply that it's intended to
 contain much more CSS than it reasonably might for the average user,
 causing a level of intimidation. It could be a nice enhancement, but I'm
 not convinced yet. I'm certainly skeptical of this sort of change at this
 point in the release cycle.

 Also, for any changes to this feature and extensibility considerations, do
 remember that there are hundreds of CSS plugins and even more CSS options
 in themes and plugins that will need to integrate with the new core
 option, in addition to Jetpack.
