To address bug #1069234
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1069234> the bcftools
package acquired, through commit a46c2e25
<https://salsa.debian.org/med-team/bcftools/-/commit/a46c2e2567ffcbac0099f102c6bcac2568f100a8>, two new dependencies:
- python3-gffutils
- python3-matplotlib
This causes the size of the package dependencies to explode from <50MB
to >500MB.
As bcftools is mostly a C software, I believe the most appropriate
approach is to have those dependencies as recommended dependencies, so
that the package can be installed in a minimalistic fashion with the
apt-get --no-install-recommends command while not affecting other use
cases, similarly to how it was done for the bwa package in commit
e3fef43e
<https://salsa.debian.org/med-team/bwa/-/commit/e3fef43e17a26dd0c1c7d7ac81333a0e9c6367b3> where perl was demoted to a recommended dependency.
