Wouldn’t it be nice if the lessons and any other coding examples posted by the Mothership contained a prominent field stating the current viability of that lesson. Also the lesson’s compatibility/incompatibility with various LC versions. 

Perhaps several fields, something akin to the dictionary’s Edition, Introduced, OS & Platforms fields.

And if a technique has been deprecated a link to the current alternative technique, if any.

Ditto for extensions & widgets.
