I think this MUST is too much, as it depends on the protocol. What we should say is that the counts MUST be available for exporters. I think this would best fit in the "readable span" wording, somewhere around /~https://github.com/open-telemetry/opentelemetry-specification/pull/1699/files#diff-ace73543d690260e873d774428419c23895283b6c31177d405816b154d1f5aa0R91

Thanks @Oberon00, I updated the note, PTAL.

I think it would be best to move this wording to the "readable span" definition, somewhere around line 91, as this will probably be the part where this wording has to be implemented. But semantically, the change looks good to me!

@codeboten Could you update this part according to @Oberon00 ?
Fixes #1698
Changes
Clarify that dropped counts should be reported from the SDK. Would love feedback from reviewers on whether or not this change should include a change to the matrix.
