However, I think it is currently too aggressive in overwriting styles.
Could it perhaps accept any style that is given in
‘org-cite-biblatex-options’ / ‘org-latex-packages-alist’ and only
overwrite it if another style is explicitly specified in the file to be
exported?
I raised a similar question awhile back, and am not sure the best approach.
But to give some context:
The current styles in the core processors are designed for portability; they are not natbib or biblatex or CSL styles, but org styles that can be mapped to those targets in more-or-less consistent ways.
This is tricky to do, in part because of inconsistencies; in particular between natbib and biblatex.
Which is to say, in some cases the style mappings might be enhanced or modified.
But I agree there should be some kind to fallback, in particular for biblatex, which has an insane amount of commands.
