Right, if something is technically an independent language module but is
used only by kubernetes, and we don't expect that to change, there's no
need for it to be in its own source package just because it might seem
tidier to us.

I doubt that this is true of all the hundreds of dependencies presently
bundled with kubernetes, however.

This is certainly a reasonable approach, if such releases aren't going
to violate the expectations of users of Debian stable.

I guess we'd have to see whether the Security Team are up for another
package which gets updated in this way.
