I just wanted to double check myself here. If I’m working on just one brake and I disconnect the line to the caliper and the fluid leaks out to the point that the master cylinder reservoir is empty, I don’t need to re-bleed all 4 circuits do I? This happened recently and I only bled the one circuit I was working on. Everything seems fine. Just want to hear some thoughts on this. Thanks.

My friend changed my brakes yesterday on a lift in his shop. He replaced the rotors and pads in the front. Didn't bleed the brakes, just pumped the pedal a few times after the job was done.
Is this normal?
I trust my friend, just remember my older cars needed bleeding.
Also remember it was a sin to open the brake fluid reservoir unless it was during a brake job.
How bad have I missed vehicle evolution?

To the OP: If the main pump chamber of the master cylinder drained, bleed the whole system.
To the second question: If all he didn't crack open any lines, just hung the calipers out of the way, then it wouldn't need bleeding to get air out. Might still need bleeding though, if it's been a year or more since the last bleeding. Brake systems get hot and cool off. Moisture condenses in the system. Brake fluid absorbs water. Everything gets rusty inside. Which is why old brake fluid looks like coffee.
