Hi, Linkerd person here. I don't use HN much these days but I was pointed me to your comment. First, thank you for your empathy. The truth is that as much as I would prefer it otherwise, this change is required for Linkerd's survival and future growth. In turn I have empathy for you—we've put you in a tough situation with this, and while with 7 prod clusters it seems fair to ask your company to help fund the project (maybe you disagree), it doesn't seem fair that the onus to push this change through your company falls on you. I know this is a consequence of how we designed this transition but I wish there were a way we could make this part better. FWIW, we do have a team of folks who are very good at working the process, and at your scale we have flexibility on terms and pricing, so I think we can make it easy in your specific situation. Some of the new features are focused on cost reduction so there is an opportunity to appease the budgetary gods.
In terms of the stability guarantees you point out, that has always been the case for edge releases. They contain the latest changes on main, and while we try to keep that as stable as possible, things can break. Everything is well-documented and we try our best to at least have you able to make an informed decision.
Hope that helps, I'm always up for a deeper chat if you want to send me an email. (At the bottom of the blog post.)
