Linux isn’t one target, but a matrix of targets: providing binaries for Linux means picking architectures, libc versions and variants, OpenSSL versions and forks, etc. against which to canonicalize. This also has downstream implications, e.g. a CPython binary with a static build of OpenSSL might contain an OpenSSL vulnerability that CPython is now on the hook for remediating (rather than delegating that remediation responsibility to downstream distributions).
Some of this complexity is also true for Windows, but Linux’s (good!) diversity makes it a bigger challenge.
