What would you like to be added:
It would be nice to have wildcard suffixes in addition to wildcard prefixes.

spec.hostnames only supports doing a full FQDN match, or a wildcard subdomain. I want to match like "grafana.*" to avoid templating HTTPRoutes. In the documentation, it is specified that Gateway API implements two exemptions to the RFCs that define a valid hostname. Why can't it be three exemptions?

This has been requested many times before, but no GEP has been proposed. As a result, workarounds are implemented. Example: envoyproxy/gateway#5370

Why this is needed:
So we can better repurpose HTTPRoutes for a general setup, without having to use complex variable substitution and whatnot. Most if not all implementations of the Gateway API already support this at a technical level.
