good question John, we are in the same position, heavily dependent on photons and particle shields for commercial use.
Whats concerning to us is I see the particle relay and shields we rely on for our commercial robotics system are already under the “legacy accessories” section of the documentation.
its a risk to our business to see particle products moved to “legacy”
So much time and money has been spent on , validating and testing hardware in the field, before putting it into production, making wiring looms up to the correct lengths, providing the correct power supply, writing the code to make the hardware rock solid, laser cutting the housing with the correct mounting points, applying for certification for the “whole product” , setting up a supply chain for the hardware, and keeping a few in stock as spares.
Its taken months to get to this point of a final design, a “legacy” does not give us a warm feeling!
