Verifiers MUST be able to validate signatures with keys ranging from 1024 bits to 4096* bits
So mail providers MUST support up to 4096 bits if they follow the latest RFC. Verifiers MUST be able to validate signatures with
keys ranging from 512 bits to 2048 bits, and they MAY be able to
validate signatures with larger keys.
I did my master thesis on this topic one year ago and found that all popular mail providers nowadays support 4096 bits, and some even up to 16384 bits.
It's not that the inline requirements make a new `.venv` directory or something, uv seems to link the packages to a central location and reuse them if already there.
