Code was added once to Debian (IIRC) and it was detected almost immediately due to code signing.

  The exploit in this case had access to the build (and presumably signing) system. That wouldn't have helped. The protection against this would have been the comparatively new efforts at reproducible builds. A modified binary, in theory, could be detected by current Fedora and Ubuntu releases (not sure about Debian or other distros). I don't think we've had an attack in practice though.

  On the other hand, Debian broke OpenSSL generation and didn't detect it for almost 2 years. That appears to have been a legitimate mistake, but it is quite conceivable that a malicious actor gets a change merged that contains a backdoor that looks like an innocent mistake and goes undetected for a long time.
