[OCCRA]: Reusing former robot chassis?

Looking at the robots this year, I got a strange sense of deja-vu...

Are teams permitted to enter robot bases from previous seasons this year? I was under the impression that the rule allowing that was made obsolete by the introduction of the C-Base kit frame. In fact, this year's rulebook states:

For instance, using a 20" long piece of square tube you just took off an old bot would be fair game, but reusing a bunch of c-base bolted together wouldn't be in the spirit of the rules.

Am I missing something here?
