Thread:Talk:ResourceLoader/Migration guide (users)/From IRC to think about - Must user-scripts add a dependency to mediawiki.legacy.wikibits?

I'd like to add some information to mw: ResourceLoader/Migration_guide_(users) - "If I use importScript in my userscript, do I have to do mw.loader.using('mediawiki.legacy.wikibits', function { /*code here*/ } or can I simply use it?"

Imagine I want to use importScript in my User:Rillke/Common.js

Will it be defined for sure or should I ensure mediawiki.legacy.wikibits is loaded by "using mw.loader.using('mediawiki.legacy.wikibits', function { importScript(...) }"

If so, add to ResourceLoader/Migration guide (users):

But keep in mind they require the mediawiki.legacy.wikibits-module.
