Tested locally, produces e.g.

    "conda-23.9.0-py38h06a4308_0.tar.bz2": {
      "constrains": [
        "conda-build >=3.18.3",
        "conda-content-trust >=0.1.1",
        "conda-libmamba-solver >=23.7.0",
        "conda-env >=2.6",
        "conda-build >=3.27"
      ]
    },

Need to update to remove other conda-build constrains.
