Not exactly - because there is no 'records' array in your request, the
existing records (if you have any) are untouched. If you have no
test2.test.com/A records, it stays that way. If you had any, they would
also stay.

Yes - comments can exist without records, and records can exist without
comments. This makes sure that your comments do not suddenly disappear
if your records RRset happens to shrink to zero entries.
