I think you are a little to pessimistic in this case. From what Dev said I understand that people with, lets say 100 captchas solved per day, will get their raiblocks eventually. No empty claims, that would be disaster.
Now you wait for the coins 24 hours, after said change you will be waiting few days (assuming 100/day) and your address will pop in the place of top 60 (at some point). I think its a good change. Less tiny transaction of 10Mrai and such -> better network response, not to mention lower load on faucet servers.

Hope that this info isn't April-fools joke
