In general, this thread has many examples of design practices that are potentially fine being written off as universally bad ideas that can't work, or design concepts being blamed as the root cause of problems that they may not have been. 14 tooth pinions do not universally fail in 3 CIM gearboxes, for example, nor do plastic hubs.

If making a general rule and building very conservatively works for your team, that's great, just be sure not to give things out as general advice without a solid grasp of the "why".

You're right, the intent of "inherently weaker" was "inherently too weak". They are weaker.
