Yes, for sure the add-ons ecosystem will fill every possible niche. However if we look at X-Plane, we can see that having good quality default avionics can actually help add-ons makers, the two things are not mutually exclusive! Many 3rd party X-Plane add-ons improve on the default avionics rather than having to develop a unit from scratch (like it’s often the case with P3D add-ons). This means that developers can focus on other aspects (e.g. failures, systems, walk around, manuals) while reducing dev costs.
