@ssande-fwd I am confused. There is no code in this extension and it is just dependent on Forward-Education/pxt-fwd-modules/fwd-solder-3b3l. Why not just add that extension to approved list?

Our product ecosystem has collections of jacdac modules. In order to allow those collections to exist independently and overlap and intertwine gracefully I am following a 3 layer architecture. It's outlined in the pxt-fwd-modules readme. The user facing extension layer doesn't introduce functionality. It groups together existing functionalities and hosts tutorial content. A side effect of this architecture is this somewhat silly situation where one of our products only depends on one module. I could break the design but then we have non-coders working on tutorials in a repo with code and increased complexity of sharing modules among different products (user facing extensions), to name a couple downsides. Instead I'm following the architecture and keeping my life simple.
