"Dark Lego, show me the forbidden connection techniques":
a leaked PDF of a Lego internal corporate document describing "illegal" connections that must not be used in official kit-building instructions
Much has been written on the analogy between lego connections and programming language syntax; that would make this illegal connection PDF the equivalent of, like, undocumented compiler features or something.
(apologies for a slightly snarky answer, but): the fact that most lego sets *come with building instructions* seems to indicate the answer is "yes"
you're probably above-average in ability to intuit connections.
I know I used the "wedge a plate edge-ways between the rows of bumps" technique frequently as a kid, and didn't know it was stressing the plastic.
For me Lego bricks are just buildig bricks that i bought in neutral packages for prototyping purposes. So i have to say i dont know which instructions are sold with the kits for building specific models and how much fantasy and creativity the people who buy specific kits do have outside of them
