Undergraduate Math degrees should cover a much wider range of mathematical topics. Many schools don’t have enough students to offer many courses exclusively for Majors so that often blurs the lines.

Topology and a few others may make the cut, but it’s much easier to share requirements with other programs so a Math degree may include courses that are required or attract students from a Physics, CS, Engineering, Music, Economics, Chemistry, Philosophy, History, etc degrees.

Depending on how you set it up “History of Mathematics” could attract students from several different majors which means you can offer it more often etc. But the same applies in reverse so CS programs can end up with more overlap than ideal.
