The README does note explain if one should use dmzadm to format a drive if using dm zone or only if one is to use a filesystem which supports zones, such as f2fs. Or if we should *always* use dmzadm format regardless of the circumstance.
Could this be clarfied? What are the downsides to not using dmzadm format on a drive and say a user just going straight to use the dm zone and then mkfs on top of it?

dmzadm is only for dm-zoned device mapper. If the file system natively support zoned block devices, it is the FS problem to format the drive accordingly to ZBC/ZAC constraints.
The README could be update to reflect this then, just to be sure. Only now that I realize it has the dm prefix did I realize this was an obvious requirement :P

And for these files systems, dm-zoned is useless.
Sure, make sense.
