T27319 allow anyone can enter it with read-only mode, but Now it looks like only a read-only mode.
In zh.wp., it have a consensus that users with some rights can remove the right by self, like the Patrollers ,Rollbackers ,etc.
Now I can't remove the rights now, just the read-only mode.
Is it something wrong?
I will investigate this. It is likely that the $canChangeAny value is incorrectly as false.
Can you please specify which of the three groups (IP Block Exemptions, Patrollers, Rollbackers) is the one that users can remove themselves from?
Never mind, I found out that all three of those group have been listed for zhwiki in the wgGroupsRemoveFromSelf variable per https://github.com/wikimedia/operations-mediawiki-config/blob/master/wmf-config/InitialiseSettings.php#L12273
Moving on to replicating that in my local wiki.
My guess was correct; the $canChangeAny value will be false if your right remove is issued through the $wgGroupRemoveFromSelf variable. I will submit a patch shortly.

@Cwek We've deployed the change.
In a few dozen of minutes, when wmf.5 will have reached zh.wikipedia (you can check that on Special:Version), you'll be able to check if all works well from your side and confirm to us it's well solved.
Update 20:35 UTC — wmf.5 is live on zh.wikipedia, so you can test this.
