It's not at all clear what the default should be when people grow the loader too big. These options exist because PXEBOOT larger than about 500k is know to be flakey, though there's no universally known good upper limit since it depends a lot on the BIOS, what it does, etc. So upping that limit is off the table (though one can if one tests it and finds that works). Some other people don't use PXE at all, so for them, disabling it makes the most sense. Still others can't up the PXE limit high enough, and for them, using the 4th loader is a good path forward. The other option is for someone to go through /boot/loader and shaving some additional space. I've found all the easy, low-hanging fruit, plus turning off all the esoteric filesystems got us down to almost fitting. Warner
