For copper water pipes though I've never seen anything happen to the copper
in a wall.

We had a gas leak in a pipe buried in plaster, I only detected it because
gas was coming out of a socket that the pipe ran close to. Turned out it
was a soldered joint that had given having lasted 33 years. The gas
engineer who sorted it told me that chemicals in the plaster react with
the lead/tin solder. I do believe running gas pipes in plaster is now
discouraged but if it cannot be avoided they should be sleeved.

Yup. I watched a gas bloke installing the new run to a relocated
job, pipes chased into wall, wrapped in some thick tape (denso)
before plasterer covered them up.
