Hey @tammy-baylis-swi, this is awesome. Overall LGTM. Would you mind adding this

_semconv_status = "migration"

to package.py for aiohttp-server instrumentation?

[emdneto]

It's been a while since I reviewed the HTTP semconv migration docs, so I may be missing something, but shouldn't HTTP_ROUTE also be set in the stable version of the semantic convention? https://opentelemetry.io/docs/specs/semconv/non-normative/http-migration/

[emdneto]

can we assert the schema_url in tests?
