Zero Ohms resistor on the Power Line

Am designing a PCB Board, in the schematics section at the power line, I added a Zero ohms resistor to VBUS power rail for cleaner power. Is adding this value of resistor a good practice at the power rail of a design, is there any tendency of the circuit not functioning as required?

Solution
I place 0R resistors not for the sake of cleaner power but for the sake of the ability to separate circuits when debugging. I believe this is the common motivation for many engineers.

Yes, it's a good practice to place 0R resistors into circuits. Especially:
• At power supply inputs.
• At power supply outputs.
• At sensitive devices' inputs and outputs.

Again, the motivation is to keep a chance to comfortably separate circuits without cutting traces or scratching PCB anyhow.
