In production environments where you treat hardware as disposable 
commodity chunks it makes sense to demand the extra effort to make the 
software components reproducible across repeated installs.  In other 
scenarios, it is just extra effort without much purpose unless someone 
else has already done it.  That is, building an RPM is always more work 
than doing a source install and often imposes inconvenient restraints 
like only permitting a single version to be running at once, and doesn't 
give you any guarantee that you won't have to repeat that extra work 
when the distribution changes.  If you aren't planning to repeat that 
install on other machines, where's the payback for the extra work and 
constraints?
