significantly improved in this release,

Yes, it looks like MIPS have got 2 ABIs - 32bit and 64bit. The choice
of the ABI is controlled through a command line option '-march=arch'.

It already isn't, why is the alignment 8 if __alignof__
(GENOME_LOC_TYPE_2) is 1?
The aligns are printed in bits. It really is okay
