It might be useful to have the option to nickname away any package 
names which come over as unwelcome advertising or otherwise 
inappropriate. In effect renaming symbols' print form so their 
package name matches their purpose from our own pov.

Any standard might include an ASDF or meta declaration form which 
states package names used by any systems, such that others who 
use/integrate those systems know what package naming conflicts they 
face, and can side step them conveniently at top level. It can be 
tricky to handle some package name overlaps.

In our glorious far lisp future, there'll be many thousands of 
interleaved systems with a multitude of package names, hence a race 
to be first to bag the choice ones (as in domain name squatters, 
sales, extortionists, self publicists, etc). Some mechanism for 
disappearing unwanted package names but leaving functional state 
identical, might be a necessity. Then we can all have our own sys and 
si roots.
