That's a good point.
Compiling and distributing binaries for all users and systems doesn't sound trivial. Only taking care of the teleport `tsh` client between windows, mac, and linux, for arm64 and amd64, sounds like a lot of boring work. Add that some users will likely download the forbidden tsh binary, that may call home and bring some unexpected bills, à la Oracle or Mirantis, it's not very appealing.
