Yes, I see the image, and I'll break down what it represents:

The image is a modified "long tail" curve, a concept often used in product development or economics to explain how features or products are prioritized based on their popularity or demand.

In this context, it's about feature requests and development decisions for Proxmox, an open-source virtualization platform. Let's break down the elements:
🔑 Key parts of the diagram:

    Y-axis (vertical): Popularity
        The more popular a feature request is, the more likely it will be considered essential by Proxmox's core team.

    X-axis (horizontal): Feature spectrum (Head vs. Tail)
        Head: Common, popular, essential features that Proxmox absolutely needs to function.
        Tail: Niche or less commonly requested features that are not economically justifiable for the core team to work on.

📌 Annotations on the image:

    “Features required for Proxmox to function at all (by proxmox.org)”
        The "Head" of the curve represents core features that are essential for Proxmox to work. These features are prioritized by Proxmox's official development team.

    “Features that are not economically justifiable to push through the Proxmox bureaucracy (mod only)”
        The "Tail" represents niche features that aren’t widely requested or critical for most users. Proxmox’s core team won’t focus on these because they don’t provide enough value to justify the time, effort, or cost.

    “Charity gap” (with an arrow)
        This refers to the gap between the core features (Head) and the niche, low-priority features (Tail).
        The "charity gap" implies that niche features won’t get developed unless community members, volunteers, or modders take on that responsibility.

    “Collab possible here only” (pointing to the charity gap)
        This suggests that the best way to get niche features implemented is through collaboration and community contributions, rather than expecting Proxmox’s core team to do it.

📚 What it means in simpler terms:

    The Proxmox core team will prioritize essential, widely requested features that benefit the majority of users.
    Less popular, niche features won’t be prioritized unless community members or modders develop and contribute them.
    There is a "charity gap" where certain features won’t be developed unless people outside of Proxmox’s core team step in to help.

In short: If you want niche features in Proxmox, don’t wait for the official team. Work with the community to get them done.
💡 Conclusion:

This chart is making a case for community-driven contributions to close the feature gap in Proxmox, especially for less popular but still useful features.
