I have been asking for over a year for server side xml that we can use to override the mod.

Features I really need to have removed but can't without making an actual fork off the original mod are:

Disable hostile / neutral grinding - why? I find it way to OP to fly or drive by any base that is not mine, with only 2-3 BOB units on my ship, they will decimate the enemy base very fast and disable other ships within a handful of seconds.

Sorry I normally only scan the pinned discussions as there is a "Feature request" discussion started by me :-)

But to answer to your question: There is already the possibility to restrict the janitor function:
If you follow the instruction under the Dicussion "Block Settings" you could create a 'Default.xml'

there you will see an entry:
<AllowedGrindJanitorRelations>NoOwnership Neutral Enemies</AllowedGrindJanitorRelations>

if you remove the relation that you don't want. Nobody in game would be able to switch them on.

Hope this helps.

And @Palad1n the server side config XML exists since nearly the first day of the mod and is described in the pinned discussion "Block Settinge" since 30. Okt. 2017 :-)
