Yet that is exactly what you propose herein...

Concept NACK. This still has the same problems BIP149 would have had, as I 
just reminded in my last email to this ML:

1) Such a chain does not indicate activation at all, leaving it unresolved and 
debatable whether activation has occurred or not.
2) As a result, it is also impractical to intentionally reject the softfork 
should anyone decide to do so.

Signalling is important to activation.

It is only jeopardized if people continue to push for a LOT=False deployment 
(or this new proposal of yours).

BIP 8 itself, with LOT=True, does not create such a risk at all.

Alternative consensus rules is exactly what you are proposing here.

More alternative rules to choose from just increase the risks. Two options is 
annoying, but adding a third for no reason is just absurd.
