Ever since session ticket key rotation was introduced in CL 9072, we've been including a prefix in every ticket to identify what key it's encrypted with. It's a small privacy gain, but the cost of trial decryptions is also small, especially since the first key is probably the most frequently used. Also reissue tickets on every resumption so that the next connection can't be linked to all the previous ones. Again the privacy gain is small but the performance cost is small and it comes with a reduction in complexity.
