The spiffe_refresh_hint parameter of a bundle represents a suggestion for when a consumer should consider requesting a new version of the bundle, see SPIFFE Trust Domain and Bundle Section 4.1.2.
SPIRE currently only considers the lifetime of X.509 root CAs in the trust bundle for its calculation of this refresh hint. Today, SPIRE Server X.509 root CA and JWT signing keys have the same validity period, but ideally the refresh hint calculation should not depend on this assumption.
