From what I have observed, it seems to be that people are more so
opposed to a hard fork when there is a comparable soft fork available
than simply opposed to any block size increase hard fork ever. From the
various threads discussing your proposal, it seemed that many would
favor it if it increased over 1 MB sooner or if it never even decreased
in the first place.

Many users are of the opposite opinion, that the block size is too
small. I understand that the decrease is to allow the blockchain size to
grow more slowly thereby allowing users to be more likely to run full
nodes. Unfortunately, I think that we are way past the point of no
return on that. The blockchain is already 100+ GB. Decreasing the block
size is not going to make that any smaller and is not going to make it
any less painful to run a full node. Given that in order to start up a
new full node will still require downloading at least 100 GB of data, I
don't think that decreasing the block size will better facilitate full
node creation. Furthermore, the current trend with ISPs (at least in the
US) is implementing data and bandwidth caps so users are still unlikely
to start up new full nodes regardless of any changes that we can
currently do.

Yes, I know deployment needs to be fixed. I was more proposing this for
comment on the modified block size schedule. I just kept the deployment
as it was originally. However, we could use a modified version of BIP 9
by using one of the top three bits and a longer locked-in period as a
grace period for all users to upgrade.

📝 Original message:Hello all,
Many people have expressed discontent with Luke-jr's proposed block size
BIP, in particular with the decrease in size that would occur if it were
to be activated prior to 2024.
I have decided to modify the proposal to instead begin the increase
steps at the current 1000000 byte limit. The increases and the time spam
of each increase will remain the same, just that the increase begins
from 1000000 bytes instead of 300000 bytes.
Furthermore, instead of a fixed schedule from a fixed point in time, the
increases will instead be calculated off of the MTP of the activation
block (the first block to be in the active state for this fork).
While this proposal shares many of the same issues with the one it
modifies, I hope that it will be slightly less controversial and can
allow us to move forward with scaling Bitcoin.
The full text of the proposal can be found at
https://github.com/achow101/bips/blob/bip-blksize/bip-blksize.mediawiki.
My implementation of it is available at
https://github.com/achow101/bitcoin/tree/bip-blksize

📝 Original message:Instead of using vanity addresses, the transactions could just use an
OP_RETURN output and express the signalling there.
However, such a system could be easily gamed by people who simply spam
the network with transactions and by miners who choose what transactions
to include in their blocks.

Armory used to contain code for handling these alerts but that was
removed after the PR removing alerts from Bitcoin Core was merged.
