Some projects seem to prefer their footnotes to be displayed without the square brackets. These projects addressed that need with a CSS workround for Parsoid the we needed to remove to fix T370512: Some wikis append a 0 (zero) after every reference/footnote in VisualEditor (due to local CSS). Now the square brackets are visible in the Parsoid read output.

Notes:
- T369614: Parsoid: explicit numbering for footnote markers might be related
- These projects seem to have introduced overrides for the i18n message that's used to compose the footnote link including the brackets [1]. There the brackets are wrapped in HTML elements with CSS classes that can be used as selectors to hide the brackets. Like for example in this patch [2].
