cache.app is not persisted between "deploys" #48319

I might have been debugging this too much already so I'm not thinking straight. I've just created a new symfony project (tried 5.4 and 6.1.7) without configuring config/packages/cache.yaml and added a simple CLI command like this:

the first time the command is executed value is calculated and saved to cache. The second time the value Is taken from cache.

After that I run cache:clear to simulate what would happen during a deploy.

Now the command is executed for the third time and there's a new value.

While debugging I noticed that during cache:clear old files in var/cache/dev are simply deleted along with var/cache/dev/pools/app which contained original value.

Isn't cache.app supposed to persist between deploys without having to configure adapter to use some other directory ?
