That's all very well, but there is no context upon which you could conclude that there is any merit whatsoever in prematurely generalising the stated problem.

And in context, which as the writer of the OP I am uniquely qualified to judge, the is no chance that the requirements will ever change from 5x6-bit values. None.

The underlying system that the problem models has been unchanged for at least 500, likely 600 and possibly 700 years. It ain't gonna change now, so the misbegotten computer pseudoscience of premature generalisation will achieve exactly naught.

With the greatest of respect to my countryman, his sweeping generalisation of 40-odd years ago has been misused and abused so frequently in the intervening period, to the point where I think that outside of the rarefied atmosphere of academia and pure research, it's true meaning has been lost.

I contend that in the modern world of commercial development, more money has been spent and wasted; more God-object hierarchies have been developed and discarded; and more development time wasted in pursuit of the premature generalisation than was ever the case with premature optimisation up to the time when he draughted his dictum.
