@ZuluPro That's for the clean up - it's always good to remove dead / unused code :)

Would appreciate if you could provide some references which document that those providers are not active / alive anymore (I did quickly check some myself and it indeed looks the companies are either dead or pivoted into a different area).

[Kami]

I'm trying to sync this up with latest trunk, but it's turning out to be a bit of a pain due to the formatting changes in trunk.

[ZuluPro]

@Kami Yes I failed too. I'm really sorry to this branch like this. Let me try to find a solution during the next week.

[Kami]

I believe I managed to address all the conflicts in #1852 (but I still need to go over the changes again and double check).

[Kami]

#1852 has been merged. Thanks a lot of this clean up!
