Again this should not be a political or business compromise model - we
must focus on scientific evaluation, technical requirements and
security.

But specifically as you asked a group of Chinese miners said they
would not run it:

Imagine if we had a nuclear reactor design criteria - we would not be
asking around with companies what parameter would they compromise on.
We'd be looking to scientific analysis of what is safe, based on
empirical and theoretical work on safety.  If we're risking $4b of
other peoples money (and a little bit of mine) I would strongly want a
scientific approach.

A closer analogy would be the NIST SHA3 design process.  With crypto
building blocks it is a security / speed tradeoff, a little analogous
to the security / throughput trade off in Bitcoin.

They do not ask companies or governments which algorithm they like or
what parameter they'd compromise on.  They have a design competition
and analyse the algorithms and parameters for security margin and
speed optimisation in hardware and software.  Much effort is put in
and it is very rigorous because a lot is at stake if they get it
wrong.
