HMRC style guide: "Avoid the shorter en dash as they are treated differently by different screen readers" [0].
But I see what you mean. There used to be a distinction between a shorter dash that is used for numerical ranges, or for things named after multiple people, and a longer dash used to connect independent clauses in a sentence [1]. I am shocked to hear that this distinction is being eroded.

That guy's style guide seems to conflict with the Cambridge editorial services guidelines - though that is for books rather than papers:
> Spaced en rules (or ‘en dashes’) must be used for parenthetical dashes. Hyphens or em rules (‘em dashes’) will not be accepted for either UK or US style books. En rules (–) are longer than hyphens (-) but shorter than em rules (—).
