Why a dedicated `<feature>` element and not `<figure>`

[dead-claudia]

<feature> and <featurecaption> are defined very similarly to <figure> and <figcaption>, and I don't understand why feature captions couldn't contain elements. And accessibility considerations are nearly identical.

Your later comments suggest you answered this, but for the record.

<featurecaption> is intended to be the accessible name of the feature, explicitly marked up. <properties> maps to GeoJSON member properties, except it can contain any HTML markup and <geometry> is a mapping of GeoJSON geometry to markup, so that it can be rendered natively and styled via CSS.
