It's not that much of problem yet. My complaints are to keep it from becoming
much worse.

Jumbo datasets are going to go away on their own as soon as a flat 64-bit file
space is put into MPE. Because Jumbos were never represented as anything more
than a spit-and-bubblegum patch and were never meant to be a permanent
structure, the use of HFS files never bothered me all that much.

However, putting the b-tree files into the HFS filespace was the one great
thing I regretted about the way b-trees were implemented. That's a lot more
likely to be seen as permanent structure (although it shouldn't be; this stuff
is still called SOFTware). Nonetheless, I want to know: "Who's idea was it to
use HFS file extensions anyway?"
