I dont know if already exists, but for Quest 4 to be modifiable by users and other companies

Title.

Example:

Change screens / lenses to better screen / lenses

Change headstrap (already exists)

Change facial interface (already exists)

Change everything about the headset, at least physically, not software

=====

Ability to change parts of future Quest 4 like a gaming desktop

For example:

Gaming desktop can change monitor, cpu, gpu, ram, pc case itself, fans, etc

Maybe get the ability to do same thing to future Quest 4?

Ability to change the lenses, entire structure, headstrap / facial interface (already exists), etc

=====

Not the same thing as my suggestion but still kind of related, but
imagine if we had this for the Quest 3S.
Quest 3S has bad screen compared to Quest 3.
Would have been sooo nice if we could have bought Quest 3S, then later bought Quest 3 lenses and attached them to 3S, instead of having to buy a completely different headset.

Kind of like how someone buys a bad gaming pc, then later gets a better cpu, better gpu, better ram, better screen, etc, instead of buying a completely different gaming desktop.

But for vr headsets too maybe?

It's a fun idea, but it's basically wish‑engineering. VR headsets aren't built like gaming PCs, and the reasons are pretty fundamental:

Optics, sensors, and tracking are tightly integrated, not modular. You can't just bolt on different lenses or screens because the entire optical path - distortion profiles, sensor alignment, passthrough calibration, eye‑tracking geometry - is tuned as a single system. Swapping one part breaks everything else.

Weight distribution and ergonomics are engineered as a whole. Changing "the entire structure" isn't like swapping a PC case. A few grams in the wrong place can ruin comfort, stability, and tracking accuracy.

Thermals and power delivery are designed around fixed components. A VR headset isn't a box with airflow; it's a sealed, thermally‑balanced device. You can't mix‑and‑match screens or processors without redesigning the cooling system.

Firmware and software calibration are model‑specific. Even the idea of putting Quest 3 lenses on a 3S ignores the fact that the headset's firmware expects specific optics and sensors. It's not plug‑and‑play; it's deep system‑level calibration.

Manufacturers don't build modular headsets because it makes everything worse: heavier, bulkier, more expensive, less reliable, harder to support, and slower to innovate.

So yeah - imagining a "Quest 4" where users and third parties can swap screens, lenses, housings, sensors, and structural components is fun, but it's not remotely feasible with how VR works today. It's not a matter of Meta refusing to do it; it's that the idea itself doesn't survive contact with reality.
