I use eval when I am sure there is no other safer way.

Mean, if I can achieve the same with declare foo="dynamically generated 
content" I opt for the later, like mapping a whole file into an 
associative array in one go instead of iterating incrementing the array 
line by line. Because I know it can be done for a declare and the 
content is generated with printf %q or jq's @sh filter.

Anyway on systems where there is a sufficiently advanced Bash available 
for these nice advanced bashisms, There are probably better all-purpose 
scripting languages available as well like Python or Perl.

For obsolete closed-source systems where I don't have control on if a 
decent Bash version is available, using the nice Bash feature is not an 
option anyway, and sometimes, yes eval will help.
