/**
 * Query interface for checking whether a named Windows feature flag is enabled for an image's
 * "born-on" Windows version — the OS version the image was originally built or linked against.
 * In observed logic, the decision is based on OriginalImageVersion for the image context plus the
 * caller-provided BornOnVersion. This is image-compat metadata, not simply current OS version.
 * A plain OS upgrade does not automatically guarantee the result flips to enabled for an existing
 * old image. It can become enabled if the relevant image/component is updated or replaced so its
 * original-image version context is newer and passes the threshold. The code path only reports
 * eligibility in FeatureIsEnabled and does not directly enable a feature system-wide.
 * So think of it as compatibility gating tied to image provenance, not a global switch that turns on when Windows version increases.
