The various limitations for a particular aircraft are a consequence of the certification design standards and how a particular applicant might seek to address these.
Be very aware that some of the requirements are quite subtle and not suited for gleaning by the typical pilot.
Like any other operation not strictly in accordance with the TC and AFM ... if one needs to do it, the airworthiness authorities have well defined protocols to address the need and, in so doing, revisit the certification and impose appropriate additional restrictions so that the proposed operation generally can be undertaken with a level of risk similar to the original TC implications.
Certainly not a matter for the line pilot to run with on a wing and a prayer basis ....
