Hi,

indeed the first two (UUIDs/generation) and the reserved space to grow
were meant to be the bare minimum to have, but indeed the other ABI
stuff is not a big deal to add and so it would be better to have it all
given that they have been asked explictly by the tools team...

...anyway till now I was trying to incrementally add new feats (like the
above) and carry-on SOME cleanup bugfixing following Sashiko reviews mainly...

...so as to simultaneously progress toward a more complete and correct code...

..but, given that the stuff in my TODOs keep getting flagged as "...ehi
this is still missing..." despite being in the cover TODOs (O_o), I will move
away from my incremental approach and I will instead aim at being at first
'feature complete' by the end of this week and then resume cleanup activities
next....

So, IF I'll have a decent feature-complete series by this weekend I will
post such a v7 (to gather more feedback), and postpone final in-deeep cleanups
in next week v8....IF NOT I will go straight for a v7 next week with
full feats AND cleanups...

(... not that I am expecting Sashiko not to find more stuff even in v8... )

Thanks,
Cristian
