Remove deprecated hass.components

[jpbede]

Breaking change

With Home Assistant version 2024.3 we deprecated the usage of hass.components. This has been removed now, custom component should be updated to import the desired components directly.

Proposed change

With version 2024.3 we deprecate the usage of hass.components and scheduled the removal in version 2024.9. Now it is time to remove the deprecated hass.components.

There are still a lot of custom integrations who have not dropped the use of hass.components, including HACS version 1, I think we should consider extending the deprecation period.

[jpbede]

Sure, sounds reasonable. What do you think would be a good extension? Again 6 months, so we would remove it with 2025.3?

Yes, let's re-evaluate in 6 months 👍

Should we do a dev blog post about it?

[bdraco]

Yes. Anything we can do to get them to switch would be great
