Feature or enhancement

Proposal:

The following code keeps a file handle for eternity and evengc.collect does not help.

>>>importtarfile>>>tarfile.TarFile("archive.tar.gz","w").add("somefile.py")

The culprit is a line that itself says that it is not needed. Indeed, it is never used anywhere.https://github.com/python/cpython/blob/main/Lib/tarfile.py#L2033

Now the example might be a rather bad style, but even a typical use case where a TarFile variable is defined and closed afterwards will also keep some stuff in memory untilgc.collect happens due to this line. Removing the line also adds a ResourceWarning to the bad style example which currently does not appear.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
