I agree negative features is not intuitive, but HINT instruction default is legal and supported, in other words, it mean the disabling HINT instruction is a feature, right?
There were also negative features in other backend. (grep `FeatureNo`) so we are not first support it.
For sure, I won’t insist on doing this, I feel it's just a friendly trade-off between user and developer.
Thanks.  :P
