Me too, I tried to download both Ram Disk and a PFS partition, and:

linux-image-5.10-rc4-X1000_X5000.tar.gz.owb 52008170
linux-image-5.10-rc4-X1000_X5000.tar.gz.wget 52008170
linux-image-5.10-rc4-X1000_X5000.tar.gz.wayfarer 119756800

And to clarify, you "can" download, but the resulting file isn't correct, it's much bigger than it should be.

EDIT: it seems that Wayfarer unarchives the gz on the fly (but doesn't change the extension)! The resulting file is the same if/when you unpack the .gz downloaded with other programs. I don't think this is a desired way usually though, so maybe if it could be disabled for downloaded files even though it might do that for some web content or so?
