I filled out one of these for Cogent to get a /24. I was being honest but all I had to put was services that requires their own IP. I even listed a few but no where near the 253.

They also never responded back and were like "what about NAT" or "what about host based routing".

Not sure what you filled out, but blocks are handed usually not to end users, but to providers that will sublease the ips to their client. So if you are asking for a block for a couple of your HTTP servers, that's a no. If you rent HTTP servers to, say, local small businesses, then that's a yes.
