I doubt that anyone would object to a 10 megabyte IPL text (and 1 should be sufficient) that would know what to do with a PDSE. The problem is the same shortsightedness that caused the MVS developers not to support FBA devices for at least the FBA file types (VSAM, PDSE, Unix, Linear, etc.). I find it ludicrous that the code that runs a vital service is a started task. Even if it makes sense for the full complement of PDSE functionality to be in a started task at IPL time, it makes no sense to not have the code needed to read PDSEs available at NIP and IPL time. For those who think 1 megabyte is a large amount of space in these days, take a look at how many megabytes of solid state storage can be bought for $100 in the consumer market, and how many more of portable spinning storage. While z reliability needs would make that storage a lot more expensive it still would probably be pennies per megabyte.
