      This is inline with Chrome (et. al.'s) construction of a two-tier system, wherein sites that are installed get "more" in various ways. We've been careful not to break things between these modes, and only hang app-mode enhancements on installation, not basics (like storage).

      What's different here is that Apple is explicitly making web-in-a-tab non-durable, whereas we've *enhanced* the durability of web-in-a-tab recently.

      maybe I am misreading your and @wanderview's replies. That would clear a lot. *Specifically* if you could answer just y/n: other than specific details abt durability/storage differences, is this fundamentally different than ff/chrome in 2 tiers/durable not permanant/use matters?

      At the limit they are the same (origin-wide eviction under pressure). What's different is that we aren't trying to apply more pressure, so incidence of eviction is *wildly* different. In all cases, if users want to keep it, we need to get them to add to install.

      I think there is a big difference between evicting under storage pressure (legit resource constraints) and deterministic wiping after arbitrary time periods.

      Specifically: Why and how it chooses to apply time to the equation in browsers (not running as pwa) is the only difference tho, right? Just confirming that I understand correctly before I ask one more question..

      Jeremy, I see what you're saying, but there's an important mis-communication in your blog post that @briankardell is clearing up: https://adactio.com/journal/16619  You say "Caches, Local Storage, Indexed DB—all of those are subject to eventually getting cleaned up." ...but *atomically*

      That is, browsers are uniform (thankfully) in treating SW registrations like all other origin-controlled storage types and deciding not to do partial eviction. That is, you can't "wake up" as a SW and find your Caches are still there but not your IDB.

      So joint eviction is good policy for app coherence. SW registrations aren't special in this way. That's a good thing. The correct focus here is on the *outlandish* reduction in durability for pages in a tab.

      And for what? Where's the model that describes the improvements gained vs. the tradeoffs? They aren't in the post because Apple (among others) keep doing ungrounded work, e.g.: https://arxiv.org/abs/2001.07421  This is why we keep focusing on meaningful details: https://w3cping.github.io/privacy-threat-model/ …

          So a good response to this change is to focus on what it gains in practice. Does it *actually* improve privacy? By how much? What does the model say about entropy removed? And how far away is a browser that implements this change from meaningful privacy?

          These questions would make it clearer how far away folks are in reality from meaningful privacy preservation, e.g. via IP addresses, screen resolution, etc.
