Added WIP tag to prevent merging until lancachenet/monolithic#87 is merged

[unspec]

@VibroAxe - lancachenet/monolithic#87 has been merged. Worth waiting for the next batch of LANs next week to further test the new steam approach or happy to take this one out of WIP now?

[VibroAxe]

I think we should leave this be for the moment, without the ua caching this merge will break the cache for anyone not running latest. I'm thinking give it 2-3 months then merge in?

Ran into an issue where creating workshop collections won't work because it tries to reach https://ufs0101.steamcontent.com:8699/ugcupload. That obviously can't work when one only have a SNI proxy on port 443.

I assume Valve expects that anything else than lancache.steamcontent.com aren't messed with now. So I ask that you consider merging this PR again to allieviate issues like this.

@Lepidopterist @mintopia @MathewBurnett anyone have any thoughts on merging this?

[mintopia]

I think we should try merging it and keep an eye on support requests and feedback. It should be OK.

[Lepidopterist]

Agreed. It's been a while.
