This affects some of the most widely used applications on the platform, including "productivity" applications such as Slack that Apple uses internally. How did no-one at Apple notice this and do something about it prior to macOS 26 being released?

I stopped using the Slack Electron wrapper as soon as Safari added support for "installing" web apps (File > Add to Dock…). Wouldn't be surprised if people within Apple did similar.

I'd sorta hope they are testing widely-used applications in the way that typical end users will experience them before releasing a new OS version.

I actually did that as soon as Safari added a pinned tab feature. I remember doing this as early as 2016.

Mind blown, this may actually be freaking useful ...

This made me try it out again since the feature was first released. Looks like they added support for Safari extensions and content blockers to PWAs in macOS 15.0.
