I haven't use those templates but I took a brief look and looks like Template:Spoiler Screen is the only one we use as a header template and for categorization. I hope that someone more familiar with those templates would comment because if there's any problems with Special:Flags it can't be undone without the Company and in the case of the Lua introduction it stopped in a few weeks.

The spoiler screen is enabled via javascript, and is not just a header in the page. The template tells the javascript when to run and categorizes the page. I believe this was why Jamie was keen on keeping it as-is as well, as it's pretty snazzy. It's adopted javascript from the dev wiki too, so it's a widely-used and not a home-grown solution (which is good).
