dhcp snooping disabled after c9300 17.3.4 upgrade from 16.12.3

I performed an upgrade to a c9300-48 running 16.12.3 and noticed that the "ip dhcp snoooping" command was not present after an upgrade to 17.3.4.

The "ip dhcp trust" commands are still present.  Anyone else notice this?

I have C9300s running 17.3.4 that were 16.12 and the command is in the running config.

Yes,  you can simply add the command back in and it works.  17.3.4 is a recommended version to be running on the C9300.  Can't believe this was missed.  I have to think that this was the expected behavour after some other change. 

If that is the case then what was the other change?  or was this just missed?

Updated 3 - c9300-48P switches from 16.12.3a to 17.3.4 and all 3 were missing "ip dhcp snoop trust" from the uplink port channel group.  Definately a "new feature".

If you add them back and test (is that working ?)
