"Superior strength" is probably just a matter taste, however I would really like to read your explanation on why you think so.

Some reasons why POSIX shells are great:
- they are part of POSIX (a Standard which is implemented by multiple OS) and therefore often available
- you can use them to compose programs written in different languages
- you can easily connect the output of one program with the input of another (pipes)

That's not an intrinsic property of Bash.

This last point subsumes the previous one. So basically, you're saying Bash is great because it's a shell?
myFunc() { (
#...
) }
1. Return values of subshells 2. Clean design 3. being a "real" programming language
The only Bash specific part was

But in fact, the usage of subshells to limit the scope and subshell return values have nothing to do with Bashisms.
