This is not what I said (if this is a straw man attempt, please don't do it).

Knowing the severity of accidentally removing data from HPA (which you
described yourself in the other mail) and also not being able to access
valid data from HPA (bug #13365) I would simply use in the installer
the alternative [*] (that I *don't* recommend as the long-term solution)
and then start working on adding proper sysyfs kernel interfaces (that
I *don't* consider not needed) and proper installer support.
[*] it would of course require passing "libata.ignore_hpa=1" to kernel
during installation time
This would result in much less hassle for users, much less support costs
for distribution and having proper in-kernel / installer support faster
than doing it the non-pragmatic way (since we would save a lot of time on
handling bug-reports and discussions like this one).
