No. Unsigned binaries are a huge security risk. Code signing ensures that the binary has not been tampered with since it was compiled, or since it was distributed, or since it was last executed. These are vectors for compromise and persistence of compromise. If a signed binary is compromised, certificate revocation provides a broadcast method for stopping further execution of the compromised binary. There are no circumstances under which I would allow unsigned binaries to be installed or used on a daily basis on any client network.
If you have a developer account with Apple the additional cost of a signing certificate is zero, and signing functionality is baked into Xcode. If you don’t have a developer account then it is a whopping 99 bucks a year to get one.
Code signing certificates for Windows are 175 for a year, maybe less if you search enough. Only a crazy person runs an admin mode unsigned binary installer. I’d be amazed if there is a modern IDE for Windows that does not incorporate code signing into the build process.
