Wonder why there was no answer to this....
,
I confess it was bait, but that was what seemed to be the format....
. Maybe someone will answer it sometime for the ones who enjoy Hanon; It would perhaps serve to save someone........

Remember, you asked for it!

In defense of Hanon one could say the following:
“Hanon was a superb teacher. His book is simply a guideline of his teaching he used with his pupils. During the lessons, he would modify the exercises and assign them in accordance with the student’s abilities and technical inadequacies.”
This may well be the case, and I have no qualms with that, perhaps Hanon wrote one way but actually directed his students to do otherwise.
However, even if this was the case, the current reality is that we have no idea how Hanon actually used the book (and judging by the instruction he left us, the scenario above is highly unlikely). The way the book is used nowadays (when it is used) is simply to learn all the exercises following the instruction in the preface. Lazy teachers love it.
Having said that, let us see the shortcomings.
The main problem with Hanon is the hidden assumption that one should learn technique on its own.
Then, as a corollary, we have the second hidden assumption that the technique in Hanon covers all bases.
Both of these hidden assumptions are completely false. Hence Hanon’s uselessness.
I have written quite a bit on these issues, so rather than repeat myself here I will direct anyone interested to the threads below (just the tip of the iceberg). We can then go on from there, if anyone wants to.
First here are a few threads that argue that technique cannot be learned in isolation from real music (and if this is accepted, Hanon can go the way of the dustbin).

The scales in Hanon follow a less than efficient fingering that has become orthodox. In particular Hanon is a believer of the thumb under method. If you do the preparatory scale exercises that precede them you will never develop true facility in scales since they are based on the wrong movement. The threads below although they do not mention Hanon provide the most efficient fingering for scales as well as the movement known as “thumb over” which is essential for playing fast scales.
