I noticed that intercepting routes are always treated as dynamic and hence never get cached. If you look at the https://nextgram.vercel.app/ example and open a photo, the ?_rsc=... responses are always served with X-Vercel-Cache: MISS, although they don't do anything dynamic. Also during build, all intercepting routes are reported ƒ (Dynamic), even when export const dynamic = "force-static"; is used. Is there any way to cache these routes?
