Why doesn't "Cloudflare 1.1.1.1" compress root answers?

At first I thought they had disabled compression:
bjorn at miraculix:~$ dig . ns @1.1.1.1|grep SIZE
;; MSG SIZE rcvd: 431
bjorn at miraculix:~$ dig . ns @8.8.8.8|grep SIZE
;; MSG SIZE rcvd: 239
bjorn at miraculix:~$ dig . ns @9.9.9.9|grep SIZE
;; MSG SIZE rcvd: 239
But then I noticed that they *do* compress other names:
bjorn at miraculix:~$ dig net ns @1.1.1.1|grep SIZE
;; MSG SIZE rcvd: 253
bjorn at miraculix:~$ dig net ns @8.8.8.8|grep SIZE
;; MSG SIZE rcvd: 253
bjorn at miraculix:~$ dig net ns @9.9.9.9|grep SIZE
;; MSG SIZE rcvd: 253
Which just makes it even more confusing. What's so special about root?
Except for the obvious :-)
