Nope, but I'm sure lots of companies are in this situation, where they just barely need the features of the lowest paid plans, end up scaling across several domains and Cloudflare makes a ton of money off a vast majority of customers that will never need their more advanced features.

Plus that means hundreds of unique domains with unique content. If you have hundreds of domains all pointed back to one site with a single forwarding rule, 99/100 could be free tier accounts.
