Did some basic grepping of 0.0.0.0, below are references that are in the components referenced in the CHANGELOG.

internal/aws/proxy: A couple tests are using 0.0.0.0 in their port binding, I'm not familiar enough with the logic to know how impactful this is to update to localhost.

receiver/awsxray: The README has lots of references 0.0.0.0 being the default address, I assume these should be updated now since localhost will be the default?

receiver/jaeger: The README has lots of references to 0.0.0.0 being the default address as well that should probably be updated. There are also a lot of tests still using 0.0.0.0.

receiver/loki: 0.0.0.0 references in README. Also, in its factory.go, there are two default endpoint variables referencing 0.0.0.0. One of these variables is unused, the other is only used in a test.

	defaultGRPCBindEndpoint = "0.0.0.0:3600"
	defaultHTTPBindEndpoint = "0.0.0.0:3500"

receiver/sapm: References in README (along with feature gate reference that needs updated since it's enabled by default), and a few different test files.

@crobert-1 I don't feel the tests are something we need to change (if anybody disagrees, let me know), but I will open a PR to update the documentation, thank you for checking this!

Fair point, they're especially still relevant while the feature gate can be disabled. I believe they'll need to be updated once it's graduated to stable though, unless I'm mistaken.

@crobert-1 Updated READMEs, can you double check?

LGTM, thanks for making all of the documentation updates as well!
