This was actually the main reason for me personally to ask about just 
dropping support for .gz files - not because I care deeply about how much 
disk space kernel.org wastes, but because the long directory listings make 
it slower for me to mentally index the directory.

I did 3* for the testing kernels (exactly because the directory listing 
got to be unreadable), and you just complained about it ;)

Of course, your complaint was that the subdirectory wasn't done 
immediately, and that the old files get moved to their own subdirectory 
later as a "archival" thing.

I just didn't want to change the location for the latest kernel.

Yeah, they also end up continually being stale.
