Mmm…  I was about to say that since I often wait on compilation
processes to validate something before committing changes or sending an
email, I'd rather be notified immediately, but updating the mode-line to
remove the indicator is actually not that informative.  I still need to
bring up the compilation buffer to know whether the process succeeded…

So maybe cluttering every mode-line does not actually help that much,
indeed.
