The way module namespaces were implemented could be used to leverage
something like this, just that you'd use it for firmware tags, not
symbols.

drivers/dma-buf/dma-buf.c:EXPORT_SYMBOL_NS_GPL(dma_buf_export, DMA_BUF);

Just that that would look like something like this, which might be
even nicer:

MODULE_FIRMWARE_GROUP("fwv1.bin", "nvidia/g1");
MODULE_FIRMWARE_GROUP("fwv2.bin", "nvidia/g1");
