Comment(by mjo):
I'm of the opinion that a `simplify` that sometimes makes invalid
simplifications is like a car whose brakes work only 9/10 times. It's
better than a car with no brakes, I guess, but unless they work
essentially 100% of the time, I'm walking.
How do I as a user know whether or not I can trust the result? Can I trust
the results for e.g. publication (or even homework)? Or should I treat
them like `random_element()`? In some cases the results can be checked by
hand, but in many, they can't -- that's why I'm using sage in the first
place!
Anyway, thanks for finding those other tickets for me. I'm ranting in
general and not at you =) I'll read through them all when I have some free
time and coffee. Maybe there's a way to make everyone happy.
