Author here. To summarize the long discussion in the issue:

1. I _love_ pure Python packages. Not everybody should be forced to use Rust. I want installing pure-Python to be as easy as possible

2. Having separate names on PyPi (with or without extras) creates confusion for libraries depending on whenever: should they depend on whenever-py or whenever-rust? If one “overwrites” the other, this adds confusion.

3. Most users expect to “pip install whenever” and start using the “fast” version

For me, points (3) and (2) weigh heavy enough to make (1) slightly more cumbersome.

But: Maybe I’ve missed something. Have a read in the above issue or add your 2 cents.

1. Is the Rust version really faster enough to warrant the extra complication? Is it faster in real-life code, not only in synthetic benchmarks?

2. I would expect `pip install whenever` to give me the pure-Python version, and `pip install whenever-rust` to give me the Rust extras. Both packages can be installed at the same time; the pure-Python package detects and uses the Rust implementation if present.

Maybe something like psycopg[binary], would it be possible to separate the rust binaries as an extra which would be imported if it exists (i.e. When installed with whenever[binary]) otherwise the vanilla python version is used. Not sure of the specifics tho, just throwing out an idea
