PTR records limit on free account

The documentation for PTR records says that if I need more than 200 PTR records then I should use a paid plan (https://developers.cloudflare.com/dns/additional-options/reverse-zones/).
I added a reverse zone, imported 256 records, changed the DNS servers for this zone to Cloudflare and the domain looks to be working properly.

Do you know what this information about the limitation to 200 PTR records for the free plan means?
Will something stop working?

I have multiple reverse domain zones that I would like to move to Cloudflare, but I don’t feel the rationale for choosing a paid plan for the DNS service itself.

Please let me know your experiences with reverse domains with more than 200 PTR records on the free plan.

Thank you in advance for your help.
