That is regrettable. Blockchain data storage limit disagreements date back to Satoshi times. Luke's 40 byte limit is by no means unreasonable. People should just chill and keep coding.
I think there is a erudite and measured discussion to be had about the reasonableness of Luke. However, Samourai consistently goes out of their way to avoid erudite and measured discussion, opting for tribalism and discord.
He is technically correct. 40 bytes OP_RETURN should be more than enough for any and all blockchain arbitrary data storage needs. Don't let lazy programmers and greedy hype riders tell you otherwise.
Yeah I don't think the bitcoin blockchain is meant to be a data hoarding NAS either.
I think the valuable anchor/notary use cases will fix this without any intervention. But on the other side, maybe a campaign to hardfork (change rules in a backwards incompatible way) to put limits on witness sizes. The benefits to miners at the expense of all other uses should be obvious. The legacy of big blocker attacks continues.
Forgot to tag @Luke Dashjr Anyway, this thread explains it fairly well: https://nitter.net/pourteaux/status/1361821176801157122
