Debian Bullseye here. Xpdf links against libpoppler102, which has GPLv2 or V3, same as xpdf.
Perhaps fact checking of the following is required. Gnome forked xpdf to have a library (poppler) for a PDF viewer (evince). For security reasons Debian maintainers are against of slightly different copies of the same code. Including xpdf-3, it was painful, but still manageable to adjust xpdf code for poppler. Since that time the upstream project released xpdf-4. It is packaged for Arch, but it is unlikely that it will appear in Debian since the code diverged even more making UI part hardly compatible with poppler.
