I like Adam Back's 2-4-8 proposal better, as it provides a gradual transition. Note that Bitfury's support for BIP 100 was based on their assessment that increasing the limit to 8MB right now is too fast. Mark Friedenbach has also warned that while 8MB is likely safe with current networking hardware, it hasn't been sufficiently tested.
I wouldn't mind accelerating Adam's schedule so that 8MB is reached in 3 years, not 6.
That might be another good candidate, especially if it comes from a respected member, like Adam Back.
The perception I got recently that people were rushing to choose between two extremes (XT-exponent and Core-1MB-forever), that's why I thought there must be a better way. This 8MB initiative, therefore, may refer to any reasonable approach that caps at 8MB for the next several years.
But there is one important thing.
If we don't have a trusted client at hand that represents a balanced approach, then when the next stress-test comes and people feel uneasy transacting, they might head for the only other eXTreme that exists out there, which eventually may as well become their (e)X(i)T from the ecosystem.
We mustn't underestimate the gravity and the inertia of the processes at hand.
Hence this thread.
