I see that we are not going to easily achieve this consensus and what should we do? What can you suggest?
seing as there is a "brand name" civil war of trust.
every implementation should have multiple releases
eg
core 0.13.2 - segwit only
core 0.13.2b - segwit and dynamic blocks
core 0.13.2c - dynamic block only
other implementation - dynamic block only
other implementationb - dynamic block and segwit
other implementationc - segwit only
And how and when are you going to realise this plan? And what if you can't achieve that?
