Because you can't change your upstream and keep your net-block. 'tis the
nature of CIDR, non?

BTW, you are SERIOUSLY missing the point. Please pardon my clue-bat.

I was answering the point, that there was no particular advantage between
one IP addr block and another. I was disproving that statement. Please learn
to understand the difference between making a point and advocating a
position. BTW, ARIN is perfectly willing to delegate portable /24's, they
just won't do you any good because of route prefix filtering, at /20 or
greater. This is one clue that you may be missing. 

Personally, I think there is a problem, but I'm the first one to admit that
I may not have the ultimate answer. Extending prefixes to /24's may be AN
answer. I wouldn't want to see it longer than that, however. That would be
inefficient. Most sites that I work with are perfectly happy with a /24, but
may not fit in a /25. Mind you, this does NOT include workstations. A /24 is
a good sized data center.

You might also catch the clue that, as folks migrate more to RAIC (Redundant
Array of Inexpensive Computers) configurations, they will swallow more IP
addrs. When I can get a 100 node Linux cluster to do the job of a Sun e6500,
for one-tenth the cost, I'll be more than happy to burn the IP addrs. Now,
try and renumber/test/redeploy that mess in a day, or even a week.

Actually, investor folk look at some of that for obvious (to everyone but
you) reasons. Which co-los are being used, as well as how many of them, make
a big statement on robustness.  However, too many locations indicate wastage
of funds. It also indicates access to bandwidth and scaleability.
