Agreed, IP is supposed to work on anything from 10Gb/s fiber to carrier pigeons. The market has chosen, IP has eaten all of the protocols that required special support from the link layer. If a link layer doesn't fit, we design an adaptation shim (I'm looking at you, ARCNET). However, this doesn't prevent us from giving advice to link layer designers for best IP performance. RFC 3819 (BCP 89) has the following to say: Subnetworks using shared channels (e.g., radio LANs, Ethernets) are especially suitable for native multicasting, and their designers should make every effort to support it. Since RFC 3819 is mostly concerned about avoiding receiving unwanted multicast, it doesn't say anything about the performance of multicast itself.
