New description:
There are a number of tickets open due to the use of `simplify_radical()`
in `simplify_full()`.
Removing it would fix at least,
* [http://ask.sagemath.org/question/767/simplification-errors-in-simple-
expressions Ask Sage 767]
* #11934 - Symbolic simplification error
* #12322 - invalid simplification of complex logarithm
* [http://ask.sagemath.org/question/1983/strange-way-to-simplify-square-
roots Ask Sage 1983]
And maybe more. Here are some related tickets.
* #11912 is related, though about `simplify_radical` specifically.
* #11668 - `abs(a+b)^2 == (a+b)^2` is now fixed by #12780
* #14305 and #14630 are tangentially related

Comment (by kcrisman):
Updates:
Removed
* #3520 - inconsistency in simplify_radical
from description, as that was not about `simplify_full` to start with.
I posted updates on the ask.sagemath questions just now.
#11934 needs review.
#12322 needs to be reworded since we didn't use the "unsafe" parameter in
`simplify_full`.
