I can think of a few reasons to stop at /24 for now, but I think the 
most important is that IMO policy shouldn't force ISPs to liberalize 
filter policy, but rather should respond to it.  To date, most ISPs 
accept PA /24's, so allowing PI blocks down to /24 won't change things 
much.  But giving out PI blocks smaller than /24 would create a lot of 
additional pressure on ISPs to accept the smaller blocks.

I would rather focus on matching PI policy to what ISPs have already 
demonstrated they're ok with for PA space, rather than having PI lead 
the way.  If ISPs decide in a year or two to start relaxing the /24 
boundary, then I think it would be appropriate to adjust the PI minimum 
as well.
