I always do. That's why my arguments weer only about technical
aspects and about general human tendencies, not about you personally.

We could do that, but IME we will not able to collect conclusive data
that way. The latest distributions are clearly inappropriate (they
always come with the latest compiler versions), and how do you tell
how many users out there use which older versions? How do we collect
statistics about that?
That's why I suggested to use the "how far in the past" criteria. We
could decide that N-year old compiler is reasonably old, and always go
with the language supported by N-year old compilers. This is an
easily testable criterion, and the decision about the value of N
doesn't need to be reconsidered too frequently.

I question our ability to verify that "virtually everyone" part.
