Umm, I was not the main instigator. Of all the 5 people in the group at
the time, I probably had the least number of changes that went into
what became OSF/rose. The main architect of OSF/rose was Melanie Weaver.

ELF has its warts too. The contortions that one has to go through to
get the last text page and first data page to be shared in the file
come to mind as a wart. These contortions are more than just the
compiler suite, and extend into the host OS. The differences between
sections and the program table is another. Not planning for 64 bit
machines and leaving appropritate holes in the structure for the 64
bit sizes to just fall in is a third.
Also the work (phone tag, etc. not actual coding) involved to actually
be able to use ELF legally without a SVR4 license was a nightmare.
