I don't really have an opinion on this, but one comment:

With more_entropy=false the uniqid() function is *horribly* slow on unix
system (because it does a usleep). Setting more_entropy=true usually makes
the call a few orders of magnitude faster. So that might be another
advantage to enable by default ;)
