They send data inside of the tunnel, which adds round trips. So perhaps resumption is useful there? It would likely be problematic if EAP-TLS doesn't support resumption, but TTLS / PEAP / etc. required it. And of course, this ignores the timeliness of the changes. I suspect that silence from the WG means that consensus is "we can afford to wait another year for EAP-TLS to be finished".
