Unless you can actually provide benchmarks that indicate a measurable difference, this is basically a waste of time. I don't see any real measurements proving there is an improvement, and I don't believe there is any technical reason for there to be any improvement either. Minification radically alters the code so much that the original formatting doesn't matter much, coding styles don't usually affect functionality, and I don't know what you mean by "compiling stability" or "reducing errors", the current code is still standards-compliant Javascript so will be parsed, compiled and executed more or less identically regardless of whether there are extra/missing semicolons, parentheses, etc.
