While I understand the wish for reducing the number of licenses (both with
regards to "pruning" and with regards to licenses that are trivially 
alike existing
licenses), I believe that it is contrary to the very concept of open 
source, which
promotes diversity and longevity.

It seems to me that the "reduction wish" is mainly a managerial issue. 
Clearly
this needs to be addressed, but the solution should not compromise the core
concepts of open source.
