if SO_BPF_EXTENSIONS is supported, than you can assume that all current extensions are supported. No need to consume one bit per feature, as all these features wont ever disappear from linux.However one of the BSDs could add a subset of the features and wish to advertise the fact. So using extra flags for non-trivial extensions could be useful.
Sorry, we're not going to accomodate this.
