No.  The lifetime is really just there to:

1) prevent the static directory from building up with files
2) workaround any issues with broken web servers that might cause  
files to be cached incorrectly
3) like any cache data, it's a good idea to clean it out every once in  
a while Just In Case

All that being said, it probably does make more sense to make the  
default lifetime something more like a week or a month instead.
