If I understand correctly, most packages like pyogrio (used by geopandas) and rasterio (used by rioxarray) already have Python 3.14 packages on conda-forge, but there is a conflict on some Python 3.14 packages being built on libgdal-core=3.11 only, while rasterio is still stuck on libgdal-core=3.10 (xref conda-forge/rasterio-feedstock#332). So might still need to wait for rasterio/rasterio#3406

All workflows now pass with Python 3.14, except the "Static Type Checks" workflow, which fails because rasterio 1.4.3 doesn't provide a Python 3.14 binary wheel on PyPI.

But, it's likely we don't have to install optional dependencies when running mypy.

Edit: I've removed all optional dependencies in c73aac8 and the "Static Type Checks" workflow now passed. Don't remember why I added them in PR #2808.

Awesome, good that we don't need to wait for rasterio anymore!
