The proportion of users believing no blocksize increases are needed is larger than the hardfork target core wants(95% consensus). The proportion of users believing in microtransactions for all is also larger than 5%, and both of those groups may be larger than 10% respectively. I don't think either the Big-blocks faction nor the low-node-costs faction have even a simple majority of support. Getting consensus is going to be a big mess, but it is critical that it is done.

Im tending to believe, that HF is necess= ary evil now. But lets do it in conservative approach:

- Plan HF activation date well ah= ead - 12 months+
- Allow increasing block size on year-year basis= as Luke suggested
- Compromise with miners on initial block size= bump (e.g. 2MB)
- SegWit

The basic idea is, as many of us agree, hard fork is risky and should
be well prepared. We need a long time to deploy it.

Despite spam tx on the network, the block capacity is approaching its
limit, and we must think ahead. Shall we code a patch right now, to
remove the block size limit of 1MB, but not activate it until far in
the future. I would propose to remove the 1MB limit at the next block
halving in spring 2020, only limit the block size to 32MiB which is
the maximum size the current p2p protocol allows. This patch must be
in the immediate next release of Bitcoin Core.

With this patch in core's next release, Bitcoin works just as before, no fork will ever occur, until spring 2020. But everyone knows there
will be a fork scheduled. Third party services, libraries, wallets and
exchanges will have enough time to prepare for it over the next three
years.

We don't yet have an agreement on how to increase the block size
limit. There have been many proposals over the past years, like
BIP100, 101, 102, 103, 104, 105, 106, 107, 109, 148, 248, BU, and so
on. These hard fork proposals, with this patch already in Core's
release, they all become soft fork. We'll have enough time to discuss all these proposals and decide which one to go. Take an example, if we
choose to fork to only 2MB, since 32MiB already scheduled, reduce it
from 32MiB to 2MB will be a soft fork.

Anyway, we must code something right now, before it becomes too late.
