A good lesson for the prototypers here, if you intend for your design to be replicated, make sure the third-party devices have multiple sellers, the more the better, so that if one goes down, your design isn't instantly impossible to build. Even then, you should have backup designs in case the exact model is not being sold anymore.
I learned that the hard way with a design in 2023, and with Galatea I have had it happen twice, once before Galatea v1 with the speaker, and recently with the Pleasure Unit, the latter because it had some other sellers, but not too many.
TL:DR, with third party devices in open source designs, make sure there are several sellers easily found, across multiple websites.
