diffs/deltas might also be a nice thing as well to slim up the bandwidth / storage if we're operating santa's list amendment
Think that deltas/diffs were a suggestion on the original CZDS working group. It is a very efficient method but would add to the time taken to produce the files. Some of the new gTLD zones have very little movenment in a month.

It occurs to me that most CZDS users are interested primarily in the collection of "ordinary" records present in the gTLD zone files, and have no intention to e.g. operate secondary servers based on the complete zone data.
In particular, the RRSIG and NSEC/NSEC3 records which can take up a significant (perhaps dominant) fraction of the zone file size, may be of little interest to most users.
I'd like to propose that ICANN make available a version of each gTLDs zone file that elides the *derived* RRSIG, NSEC and NSEC3 records. Doing this can save significant tranmission costs on the ICANN size, and storage/processing costs on the CZDS user side.
If some users want the zone files, RRSIGs and all, those can continue to be available.
[ Please DO NOT elide "DS" records, these are not "derived" data, signal which delations are signed, and typically do not take up nearly as much space as RRSIGs. ]
It would make the files a lot easier to process and would reduce the bandwidth requirements for the CZDS. Currently, the daily download of zones is around 7GB. Deltas would considerably reduce that download.
