You mean software that has to be deployed locally? Like the example I gave?

It's actually worse. The longer you take to get a fixed version out there, the more people will install the buggy version. As distribution is more difficult than just merging a Github PR, that buggy version will live longer on live systems. And before you say "but it's on the developer/DevOps/sysadmin to test," I point you to the countless CVEs where this didn't happen.

Knowing this is the situation, it's unconscionable to leave a faulty build on live for longer than necessary, when you can rollback the change with limited risk.
