BTW, we worked on reducing the install memory footprint recently:

I think I read it, somebody pointed at it before :-)
For this I collected some numbers (see attached file). The things mentioned there have all been implemented meanwhile.
You can see that tumbleweed (I would place leap close to tw) needs more space than sles12 but not _that_ much more. And as sles12 _does_ install on 0.5 GB machines, it's not clear why 0.75 GB should be a problem for leap. Even if you account for larger repositories.
It is true that there are hooks still in linuxrc for quite some counter-measures including activating swap and even creating a swap file on a windows partition (haven't tried this for a decade but the code is still there...).
But the memory limits for those haven't been updated for ages. Mainly because it is a bit unpractical: you have to tune them again for every release and every architecture. And yes, it changes from beta to beta.
So, basically we've given up on the fine-tuning and just say 'go for 1GB'.
Makes sense.
That said, I think that leap failing to install on 0.75 GB would be a bug.
