Clarification about the "routerboard" package

RouterOS General
1

In our network we have a lot of RB133 as CPE, and we are trying to install on these 3.30 ROS version.

But with this version, we know, the CPU will stress to much.
So, i’m trying to disable all the packages not indispensable for us.

Therefore, what is exactly “routerboard” package?
I read “support for RouterBoard-specific functions and utilities”.
What happens if I disable it? What will not work anymore?

Thanks.

All the functions and settings from /system routerboard will be unavailable from RouterOS.
