Oracle: Unbreakable (YMMV)

Oracle's latest CPU mentions, Oracle will proactively create patches only for platform/version combinations that, based on historical data, customers are likely to download for the next Critical Patch Update. We create patches for historically inactive platform/version combinations of the Oracle Database and Oracle Application Server only if requested by customers.

So, it reads like, if you're running a popular build, hurray for your Unbreakable patch. If not, you're going to have to wait N years for Oracle to create an extra-special patch. In other words, you're in the the Unfixable support model. Congratulations!
