Industry standard or not at all.
Proprietary parts are a headache waiting to happen. Modular design is one of cyclings' greatest strengths. It leads to longevity, value, utility, low cost of ownership & repairability. Any genuine innovation to these ends has a tendency to become adopted; to become moreorless "standard."
Simply put: Proprietary components are a liability to future use & chain you to single source provisioning at great freedom & cost.
Choose wisely.
