@AaronSterling actually I was already doing like this (“create separate own copy.config.js file”), but I use the word “overwrite” to describe that, which wasn’t clear at all I notice now, thx 
I have now updated my own component README and also linked yours in EXAMPLE: Integration StencilJS Web Component in Ionic App
P.S.: btw. I do the same, “create a local copy.config”, for example to deploy the fontawesome (v4) fonts to the assets folder.
