I disagree :-)

If you have different pools for full, differential, and incremental 
backups with different retention times you end up with complete 
catalog information for all available jobs, but can have - for example 
- monthly full backups going back one year, weekly differentials 
covering eight weeks, and incrementals for the last two weeks. 
Something I like to implement for my customers. And of course I 
believe this does make sense ;-)
