Not trying to necro here, but maybe we could get an offical response,
if this mod is fine with FS for now & maybe some warning, IF and WHEN it is not?
So one maybe clear excess slots, BEFORE something unfortunate happens.
Just asking for a friend… 
Hey, as the use of mods is to be done at players own risk, I can’t guarantee that there will be any warning if any action will be taken against this particular mod, and Fatshark will not be able to help with accounts losing gear, characters, or other data as a result of using it as per our policy.
that atleast means no bans?
Reading between the lines correctly, I think…
→ There currently is no policy against this mod
→ There doesn’t seem to be a policy against this mod coming at the current time
→ Fatshark reserves it’s right to change this stance should they notice the mod causing issues
→ Catfish doesn’t know if the team plans anything against this mod, but her current knowledge says no
→ If the mod stops working, they will also likely not refund gear and such
TL;DR: Soft-sanctioned, but no guarantees
i don’t want speculation, i asked for confirmation specifically. 
Oh you won’t be banned for using the mod!
Thanks for the reply.
