You’re right. I think what you’re describing is “trunk based development” and it’s much better.

Maybe I’m overly cynical but I think git-flow was popular largely because of the catchy name and catchy diagram. When you point out that it has some redundant or counter-productive parts, people push back: “it’s a successful model! It’s standard! What makes you think you can do better?”

There’s a nice write-up of the trunk-based style at https://trunkbaseddevelopment.com/ that you can point to as something better.

Correct. If you can always either fix it forwards or roll back, which you should be able to unless you're building software that needs to go out in releases with versions tracked separately that need to keep getting fixes, trunk-based development simplifies everyone's lives greatly.

I've never seen an organisation that insists on release branches and complicated git merge flows to release their web-based software gain any actual benefit from it that isn't dwarfed by the amount of tooling you need to put around it to make it workable to the dev team, and even then, people will routinely screw it up and need to reach out to the 5% of the team that actually understands the system so they can go back to doing work.
