I have also been testing the optional mod support in Convoy multiplayer and it seems to work all right. So I am pleased to say I am confident on keeping this tag enabled for the mod.
It's a great opportunity to make multiplayer sessions accessible for more players.Of course, keep in mind if you join a session without a visual optional mod enabled that the host has enabled (e.g. a truck mod), you can expect to see green boxes.
If you want to a host a Convoy and allow those who don't have this mod enabled to join, please tick this checkbox when creating your Convoy.
For those wanting to join a Convoy where a host allows optional mods, please remember to tick this checkbox under the Advanced filters when browsing Convoy sessions.
Without further ado, here is the update!

v22.53
Default parking brake sound reworked to use sounds based on the International Lonestar.
It now has a corresponding air sound that is audible from the outside camera when applying the parking brake.
The trade off is that the air sound doesn't attenuate by distance, however it is affected by the truck cabin soundproofing now.
To use this in a truck mod, please use these lines in the interior sound configuration:
sounds[]: "stick_park_brake|/sound/truck/default/interior_stick_park_brake.soundref"
sounds[]: "stick_park_brake_off|/sound/truck/default/interior_stick_park_brake_off.soundref"
