// The general list of blocked ports. Will be blocked unless a specific
The reason it’s called unsafe is not because it’s unsafe to Chrome, it’s because it’s unsafe to those services, where an attacker may try to use Chrome as a proxy to attacking services on those ports. More explanation here:
So, why does Chrome refuse to connect to some ports? Because the Google engineers has gone through the list of well known ports, and worked out how tolerant the protocols that use these ports are to being sent HTTP requests, and if they are tolerant, they’ve marked it as unsafe and so blocked it, to prevent Google Chrome from being an open proxy to a secured network. Should all web browsers do this? Probably.
