[issue40060] socket.TCP_NOTSENT_LOWAT is missing in official macOS builds

[Ronald Oussoren]

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

The active PR on bpo-41100 will make it possible to build the installer on the latest version of macOS (which will be needed to be able to provide support for "Apple Silicon").

IMHO it is not necessary to remove unavailable constants, on some platforms (in particular Linux) some of the constants might not work because the relevant kernel module is not loaded. That's something you can only find by actively probing, which is too expensive and error prone. 

I propose closing this issue: the installers are what they are for a reason, and a better solution than proposed in this issue is on its way.
