no problem normal washer wear, can happen to any valve.

a friends garden hose faucet leaked like that, i showed her how to fix
it on mine a few years ago, mine was leaking too.

friends husband was skeptical, then amazed it worked so well. hers
hasnt leaked again

you might have to do this highly complex and technical job again in a
few years

tighten packing nut a little time 5 seconds
