[NTG-context] How to start the demo in modules

Hi, MKII uses \doifnotmode{demo}{\endinput} to enter the demo mode in modules. I see that MKIV now switched to \continueifinputfile{s-something.mkiv} The question arises: What should I suggest to a module writer for a relatively simple file that doesn't use any MKIV features and provides just the module file t-something.tex? Is it OK to keep using "\doifnotmode{demo}{\endinput}" also in MKIV? Thank you, Mojca
