    * Linux: CentOS 7 or newer; more specifically GNU libc >=2.17
    * OS X/macOS: 10.13 or newer
    * win-32 deprecated soon...ish.
    * Needed to support, e.g., MKL >=2020, PyTorch 1.8, etc.
* Consider reserving `__` prefix for virutal packages.
    * Nvidia: virtual packages for drivers
    * Virtual packages as plugins, possibly defined in ``.condarc`?
        * https://github.com/conda/conda/issues/10131
* Think through how to support CPU- or other hardware-specific features
    * Want to avoid subdir explosion
    * Virtual packages probably a cleaner approach
    * Library for detecting CPU features
        * https://github.com/workhorsy/py-cpuinfo
* "source" subdir, caching sources
    * Need to preserve the source archives (e.g., bzip2, ICU)
    * bioconda has cache of tarballs via Galaxy project
    * updates conda-build to fallback
* Ways to pass arguments to activation scripts
    * E.g., munge `*FLAGS` to set `-mcpu=`, `-march=`; `-std=cxxNN`; Windows SDK version
    * Should be exposed as machine- and human-readable metadata
* Design doc for 5.0 (action item for CHL)
