If you copy/paste the commands, the interruption is very minimal, would expect less than a second, and DHCP will retry if it doesn't get a response.
You can see this as a 'safe guard' as well, because it prevents you from making changes to an operational service and potentially introducing an issue. It looks to me carefully designed like this, and you could ask the other vendors that you know that don't, why they haven't.
An alternative solution is to use DHCP relay (ip-helper) instead of doing DHCP server on your switches. Centralized DHCP provides better visibility and control over the clients and removes 'micro management' on each of your switches, and resolves the redundancy issues that you have with local DHCP servers. And you probably never need to change the settings on the switch anymore.

Wanna ask whether that "dhcp-server disable" is mandatory for
every ArubaOS switches
or
only on certain model or certain version
AFAIK other brand simply changes without need to disable dhcp first.
Correct me if I am wrong
Disable dhcp server will disturb service momentarily
