Re-reading the note, I think my main concern is on the proposed clarification:

> For example, budget data for different years or observations from different sensors should be modeled as different datasets

This looks to me possibly conflicting with the preceding and following sentences:

> In any case, all distributions of a dataset should broadly contain the same data.

> The question of whether different representations can be understood to be distributions of the same dataset is use-case specific, so the judgement is the responsibility of the provider.

The clarification seems to say that "budget data for different years" and "observations from different sensors" are both to be considered as different data, which might be questionable (time series are supposed to follow the same data schema, data collection methodology, etc., whereas data from different sensors may have  nothing in common).

Moreover, the clarification seems to contradict the second sentence - the one saying that it's eventually up to the data provider to decide.

Said that, I do think the content of the note would be more in scope of a primer. The current definition and usage note of distribution is, IMO, good enough to clarify what it should be used for:

> A specific representation of a dataset. A dataset might be available in multiple serializations that may differ in various ways, including natural language, media-type or format, schematic organization, temporal and spatial resolution, level of detail or profiles (which might specify any or all of the above).
> This represents a general availability of a dataset. It implies no information about the actual access method of the data, i.e. whether by direct download, API, or through a Web page. The use of dcat:downloadURL property indicates directly downloadable distributions.

BTW, I have also a concern about the last two paragraphs of the note - I reported this in a separate issue (https://github.com/w3c/dxwg/issues/809)
