common.sign_apk() docstring says it zipaligns but it doesn't

The docstring for sign_apk() says "Sign and zipalign an unsigned APK [...]".

But apksigner doesn't zipalign (it does realign, but only if an entry is aligned in the unsigned APK and for some reason would not be after signing).

It seems most apps get zipaligned during build automatically anyway, so I have no idea if it actually matters, but the docstring is wrong.
