I'm not sure how best to update without making this big PR even bigger, but the section with the table of attributes will need to be updated in some way (starting on line 114 that still references Server Spans). It may be worth having two tables - 1 representing old, 1 representing new. I'm happy to help craft that table in a separate issue and we can issue a follow-up PR. I would recommend at least a small change to that section though along the lines of "These are the attributes in the default behavior using only experimental attributes".

I left the old table as-is for now. The new semconv is documented already in the semconv repo. When we remove this fallback the old table will be removed entirely. Would that be sufficient or do you think we need a table here as well?

I've gotten a lot of requests for showing what attributes are included in instrumentation, especially as different instrumentations (and languages) are in different versions. Folks also ask about other attributes (non-semconv) in different instrumentations, e.g. express.name, though that's less relevant for http here. The semconv might be in the semconv repo but it doesn't specify what we include, and may not be easily navigable by end users. Ideally we autogenerate a list of attributes vs handcrafting a table though, but with the table already there we may as well use it.


Prior to version `0.54`, this instrumentation created spans targeting an experimental semantic convention [Version 1.7.0](https://github.com/open-telemetry/opentelemetry-specification/blob/v1.7.0/semantic_conventions/README.md).

This is the recommended configuration, and will soon become the default behavior.

thanks for pointing this out - I also had a quick look and it does not seem like there's a easy way to do it 😞
I think using the library is justified.
