Seven seconds is already pretty fast. Might have warranted some profiling and a brief attempt to speed up the parts of the compiler that your usage hits, since that could potentially be useful to everybody and thus magnify the value of cutting one second off a build. But this? Was a cool learning experience, no more, no less.
7 seconds is plenty fast enough to make “watch” the cheapest and most reliable solution to the speed problem.
