When you add that many DNS records have very short TTLs, i.e. 5 minutes, if you 2nd attempt more than 5 minutes, then any DNS caching benefits you might have are lost. There are many parts to all this.

People with sub-optimal greylisting configurations often have sub-optimal DNS
configurations as well, because cluelessness is often pervasive. Film at 11.

Move along, nothing to see.

Good point, but imagine if a BCP was developed, eventually even the layman operators will inherent the result and naturally their software will/can support a retry=hint automatically generated the dummies have nothing to do with (if only to just enable it if the software chooses to have it default off).

In the end, we network benefits or at least has the potential now to leverage new information.

(Though I agree that an Informational RFC documenting the BCP might not be a
bad idea at all)
