Currently if you use -t typst with --citeproc, you'll get a typst #bibliography and native typst citations, which isn't desired. See #10655. Using -t typst-citations is required: this disables the native typst citation syntax. But this is pretty counterintuitive and is likely to trip up users. It would be good to disable the citations extension in the typst writer automatically when --citeproc is used.
