Seems like I have an uphill battle here, LOL
The truth is that per design it is allowed. It is not any worse than running an arbitrary RPN program that makes use of plug-in modules and inserting the wrong module that happens to have same XROM number. A random function is executed. As long as the module inserted isn't the PPC ROM, you are reasonable safe.
We agree on all those points.
In fact the original design was somewhat weak, IMHO. Simply marking modules that HP sold with the same XROM ID with an "X" in the title was a feeble attempt at managing this 'issue', but most likely the core OS behavior was set by the time this was a real world issue. In the early 41C days, the odds of users buying 4-5 HP Application ROMs was surely considered unlikely, to say nothing of the 3rd-party market and with all that, 32 is hardly enough IDs.
Still, at this point, the 41X has made 'trying out' ROMs so easy and quick, that many folks will simply plug them in to see what happens, so a stern warning is a good thing to call attention to possible problems or at least inconsistent behavior.
Adding information showing the XROM IDs will help here, but I'm confident it will still be an issue.
But thanks for the discussion about this, it helps to explain it to readers and to understand different views about the issue.
