Package: mupdf Version: 1.15.0+ds1-1 Severity: serious mupdf is AGPL licensed and does not come with an OpenSSL linking exception. According to ftp-master this is a serious violation (https://ftp-master.debian.org/REJECT-FAQ.html).
Not linking with libssl does not lead to any package errors and only slightly reduces the package's features. I removed it in https://salsa.debian.org/koster/mupdf/merge_requests/2
