Thanks! Some questions:
- "setup an interwiki with transclude set to on" - how is it different from the next point, "set $wgEnableScaryTranscluding to true"? (Sorry if it's a silly question, I've never set up a wiki wgEnableScaryTranscluding myself).
- place {{raw:Interwiki:Template Name}} where you want to use it - What do the words "raw" and "Interwiki" refer to here? Is "raw" a part of wikitext? I've never encountered it.
Also, other than https://template.miraheze.org/wiki/Interwiki_transcluding_templates, is there anything else written on this topic? I was doing a bit of homework in October while I was writing the first drafts of Global templates/Proposed specification, and all I could find was https://template.miraheze.org/wiki/Miraheze_Template_Wiki, which mostly recommends importing and not transcluding, so it's not very different from what we have at Wikimedia.
Finally, the page "Interwiki transcluding templates" says: "Don't use the method on this page until it's fixed and the above warning has been removed". So does it actually work at Miraheze?
Anything you can write about the problems you have with functional bugs, caching issues, localization challenges, and so on, can be useful for implementing better global templates and for all MediaWiki users.
