I'll be clearer then: I think this is a bad ABI. In your reply, you justify
this bad ABI by implementation motivations.

I don't care about the implementation, I care about the ABI, and
I feel that your reply is not addressing my concern at all.

Moreover, double-negative boolean options (disable-X=false) are confusing.

Thanks,

Mathieu
