Oil leaking from drain plug?

i do my own oil changes.

i brought my 2015 mazda3 to the dealership for a recall.
they did their usual 360 degree check (or whatever they call it) in addition.

the service rep said the mechanic found slight oil leaking and suggested that i replace the drain plug/washer.

i can see it not being tight. just tighten it, right?
but to buy a new one and replace? ???

How does an oil drain plug/washer fail?

Before trading in our Acura and previous Mazda for our current 2017 hatch, I never replaced the crush washer once on either car after doing two dozen plus oil changes on the two cars with 75K and 95K, respectively. No leaks. I was one of the lucky ones. Installed a fumoto valve this time around.
