There are some efforts in the physical world to de-siloize products/artefacts that might be worthwhile as an analogue https://solar.lowtechmagazine.com/2012/12/how-to-make-everything-ourselves-open-modular-hardware.html. The progressive levels of user involvement is probably relevant to many UXs. (take out "solar" from the URL if you want to go to the conventional, non-solar-powered version of the website)

I’ve felt a few times that it’d be lovely if general stuff that isn’t especially designed for modularity, or even for reuse, nonetheless, tried to kind of fit in to a system of interoperable norms. So, it could just be not making something with a dimension of 100.5 mm, because that won’t quite fit in lots of places – instead go a little under. But it might also be adding some mounting holes or studs on to something at a standard spacing. It would just be a kind of expectation to try to engineer in more opportunities for things work together.
