> enable 'm' extension with passing mattr=+m After this patch, it would be -mattr=+m2p0.
It's not obvious to me that support for extension versions should mean or has to mean that we always explicitly specify the version. Why can't we keep supporting the option `mattr=+m`, which would be mapped to `mattr=+m,+m2p0`, or whatever the current default `m` version happens to be?
