I don’t think Epic will do it soon, because it’s a thing that useful only for Win developers without Steam.
As for “Use Chunks” - it is really hard feature. There you need to assign each (each, one by one!) asset to appropriate PAK.
So, doing packaging using .BAT is pretty nice thing. Anyway, you need to deploy new version of the game to servers and the easiest way to do this = .bat + WinSCP (if someone need explanations “how to” - I’ll do it 
)
Benefits of using BAT:
- Deployment process is one click (double click
). By executing the script you cook the game, generate PAK’s, upload game to the server - You can assign one or several asset folders to appropriate PAKs
- There is possibility to publish/update something on the website through CURL
