True.

BIP 100 and 101 could be combined.  Would that increase consensus?

- Miner vote threshold reached
- Wait notice period or until earliest start time
- Block size default target set to 1 MB
- Soft limit set to 1MB
- Hard limit set to 8MB + double every 2 years
- Miner vote to decide soft limit (lowest size ignoring bottom 20% but 1MB
minimum)

Block size updates could be aligned with the difficulty setting and based
on the last 2016 blocks.

Miners could leave the 1MB limit in place initially.  The vote is to get
the option to increase the block size.

Legacy clients would remain in the network until >80% of miners vote to
raise the limit and a miner produces a >1MB block.

If the growth rate over-estimates hardware improvements, the devs could add
a limit into the core client.  If they give notice and enough users update,
then miners would have to accept it.

The block size becomes min(miner's vote, core devs).  Even if 4 years
notice is given, blocks would only be 4X optimal.
