In a term, consensus mechanism. Until consensus is reached on protocol changes, the status quo prevails.
But what's the status quo? Certainly not SegWit/CT/LN et al. Is it?
The status quo is a 1MB block size limit as a hard rule. Segwit, as a soft fork, doesn't remove or change consensus rules. And miners can soft fork whenever they please -- that's not up to users, nodes or developers.
How are CT or LN consensus issues?
