Final Package Has Additional Constraints Not Specified in meta.yaml

What happened?

I have a conda package I build using conda-build, where I specify the following dependencies in our meta.yaml file (somewhat simplified):

requirements:
  build:
    - {{ compiler('c') }}
    - {{ compiler('cxx') }}

  host:
    - python
    - setuptools <63
    - numpy >=1.18,<1.24
    - fsspec >=2021.09
    - boost-cpp =1.82
    - libcurl
    - hdf5 >=1.10.*,<1.13.0a0=*mpi_mpich_*
    - h5py
    - mpich >=3.3,<4.0.0a0=h*
    - mpi4py

  run:
    - python
    - {{ pin_compatible('numpy') }}
    - fsspec >=2021.09
    - libcurl
    - mpich >=3.3,<4.0.0a0=h*
    - mpi4py

But the output package has the following dependency version constraints (for Python 3.10 and Linux x86):

fsspec >=2021.09
hdf5 >=1.12.1,<1.12.2.0a0 mpi_mpich_*
libcurl >=8.2.1,<9.0a0
libgcc-ng >=12
libstdcxx-ng >=12
mpi4py
mpich >=3.3,<4.0.0a0 h*
mpich >=3.4.3,<5.0a0
numpy >=1.23.5,<2.0a0
python >=3.10,<3.11.0a0
python_abi 3.10.* *_cp310

There are 3 inconsistencies between the specification and actual constraints:

• libcurl is unconstrained in meta.yaml but is constrained to >=8.2.1,<9.0a0 in the final output
• mpich is constrained twice in the final output, where the second constraint is invalid
• numpy is incorrectly constrained to >=1.23.5,<2.0a0 in the final output but should be >=1.18,<1.24

Any ideas what might be causing these issues?

Additional Context

I build this package for 3 Python versions (3.8, 3.9, 3.10) and a couple of environments, but the issue appears in all builds. I'm generally happy to modify the dependency constraints around, but would like to confirm if this is a bug or expected behavior first.
