The problem is that LE is being used as plumbing. I noticed MIAB was using LE because I recognise that SSL-out-of-the-box is something interesting, and I investigated. But I wager most people who use it will have no idea. They just install it, and "it works", as it should. great. What's HTTPS? That's the entire point of tools like MIAB, mind you:

I'm just choosing MIAB as an example here. This applies to anything that LE now enables. People don't know they're using LE, much like IOT users don't know they're using HTTP/1.1. It's part of the plumbing. What's an ACME client? What's LE? What's v1?

This is probably happening for IOT devices across the globe just the same. A 2y expiration date is an order of magnitude too low for plumbing. Imagine if we suddenly decided to phase out HTTP/1.1 within two years.

We have to recognise that we are shoving HTTPS down people's throats. Pretty soon, HTTP will get big f-off warnings. OK: fair enough. However, if we're doing that, we should also provide a viable alternative, with the same reliability. Otherwise, HTTPS is a massive step backwards for the decentralised web. LE is that alternative, but not if we start breaking backwards compatibility every 2 years.




Again, I'm not saying that the two year expiration date means "v1 stops working".

Rather, "after this point, no new domains may setup via v1", so any existing certificates and installations are grandfathered. Two years is sufficient for MIAB to update their software and distribute to users.

>LE is that alternative, but not if we start breaking backwards compatibility every 2 years.

Not what I'm saying either. They have a v2 now, we don't know if they need a v3. And they want to keep v1 running for a while.

But there will be a point where v1 will need to be switched off, similar to how modern browsers have switched off SSLv1 despite a lot of people still having servers running with that.

LE will, at some point, have to decide between keeping v1 running or moving away from old protocols to be able to evolve. And that cannot be infinitely pushed backwards.
