On a system which uses those, yes, though many people aren't
self-building anything and just use packages, in which case sysclean
does a pretty good job (especially if restricted to ^/usr/).

And when people are building things themselves, they often break
across OS version updates anyway. Not all the time, but around every
2-3 releases is not unusual.
