A lot to unpack here.
> The fact they will remove the option for us node runners to decide what will go trough our nodes is shady. I want option to change OP_RETURN value in settings.
The latest version of the pull request only deprecates, but does not remove the configuration option.
> Increasing the Blockchain size by allowing arbitrary data transactions. It's true they'll pay more but that won't stop them and major miners arent against that.
OP_RETURN data is written to output scripts. Output scripts are not subject to the witness discount. More OP_RETURN data would likely reduce blockchain growth, so as I was asking in the above post, I am not sure where this idea is coming from.
> The cost of running a node will increase because 2TB drive will not be enough if they keep spamming the Bitcoin.
Blocks are limited to 4'000'000 weight units. OP_RETURN data bytes weigh four weight units, so a block filled with OP_RETURN outputs would come in close to 1MB, which is significantly less than the latest 30-day average of 1.64 MB. It’s unlear to me how more OP_RETURN data would increase the blockchain growth.
> Look at the Ethereum for example. Their full archive node requires 12TB of disk space I believe. It might be even more today. And even they have OPTIONS to run 3 kinds of nodes.
No clue, they have made a lot of strange decisions, but I don’t see how it’s relevant as the things that lead to bloat there are completely different.
> I'm not seeing the reason why in the hell #Core devs need to remove this option. Leave it there. I'll decide how much shit I want to broadcast.
I think there have been several books worth of explanations written at this point, so I don’t think it’s useful to elaborate, but if you are earnestly interested, I can provide a few links.
> I hope people won't blindly update to new core 29 release after knowing what that brings.
Bitcoin Core 29.0 came out in April and did not change the OP_RETURN limit. If the currently open pull request should get merged, the change would at the earliest be released with Bitcoin Core 30.0 in October.
