I just had a thought... are the extenders EF to RF with extender? I can’t tell from the pictures whether it’s a red stick or a red dot on the top. But the protrusion into the lens makes a lot more sense if it’s going directly into existing EF telephotos. Or at least one can hope that a true RF extender won’t protrude into the lens...

That would be great, but I don't think it is.  If it was it seems like you would need 3/4" for the RF-EF part, like the adapters and then the glass for the 1.4x.  This one looks too skinny and I haven't heard anyone mention EF in relation to it.
