Thank you. Indeed, the CSL variables for translation/reprint and the like are the same of the old BibTeX files, now deprecated by the Biblatex format. This new  format is much more practical, but I agree that a conversion would be a bit heavy. A sort of pre-filter should read the related entry, extract the needed data (e.g. title), add data with a new label (e.g.  original-title), and reshape the cited item. Not difficult, but a bit cumbersome. Do you think that a proposal would be worth submitting?

To the best of my knowledge, CSL does not provide any mechanisms for dealing with relations between different items. (For example, that’s why pandoc-citeproc needs to pull all the data from a `crossref`ed item and fold it into the `crossref`ing item when translating from bibtex/biblatex to CSL JSON/YAML.)

CSL-M has “`cs:alternative` to add supplementary reference information to a cited item, such as a translation or reprint” (https://citeproc-js.readthedocs.io/en/latest/csl-m/index.html#cs-alternative-extension), but even if we were to consider adding CSL-M extensions to pandoc-citeproc, we would still have to fold all the information from a number of different biblatex items (translation/reprint; orig. lang. version; earlier print; …) into one CSL JSON/YAML item.

Anyone who sees this a unsatisfactory could of course submit a proposal for enhancing CSL itself (https://github.com/citation-style-language/schema/issues).
