I think it's perfectly reasonable to have tuning knobs that are reserved
for experts or people with too much time on their hands. I just think
that we already have a mechanism for that via --param. For --param the
docs say
The names of specific parameters, and the meaning of the values, are
tied to the internals of the compiler, and are subject to change
without notice in future releases.
I think that is the kind of thing you are talking about. I think that
for compiler tuning knobs we should use the mechanism that already
exists, rather than introducing a new mechanism of undocumented -f
options.
