Look how easy was the whole procedure. You just sent an email and boom next day your application's port was registered by IANA. Nowdays you must have a team of academics backed up by Google to apply for that.
I've still got that Class C registered, but it hasn't been used in years, and I'm not entirely sure what to do with it.
Nowadays you should need 2 teams of academics backed up by 4 companies and 2 governments to change anything.
I'm not kidding. The internet of today should be like democracy: really hard and slow to change because sudden change is very disruptive.
