Prevents air from getting in the line. You should have a refiller on the master cylinder anyway to prevent the reservoir from running dry.

That's what I do. A pair of needle nose vise grips with some rubber hose slid over the jaws. You don't need a lot of pressure. Just enough to close brake hose up.

When the pedal is fully released there is a fill port open to the reservoir. The initial pedal travel pushes the piston past the fill port, which keeps fluid from draining from the reservoir.
This is how self-adjusting hydraulic systems adjust to the changing volume.
I keep reading advice to crush the hoses to keep fluid from flowing. That's long obsolete, and risks weakening the hose reinforcement fibers. This is the braking system, not a place where you want to be a hack mechanic.

I'm sure it's usually fine and an argument will be made that people have done this without issue for years, but it's not worth the risk to me. I've only had to replace two calipers in my life and neither leaked to the point I felt I needed to do anything about it.

Put a plastic zip lock on the reservoir and tighten the cap over the plastic ziplock to create a complete vacuum. Then open the caliper feed, there will be nothing in the line to pull fluid from the master.
That is what I did when I replaced a caliper.

I never replaced brake caliper but I think this method is better than pinch the brake line.
