Please excuse my profanity of mentioning zsh in this list, but I really 
think features and behavior convergence can benefit end users in 
multiple ways, especially when expanding beyond the POSIX sh scope.

What direction has taken zsh with expanding associative array indexes?

I don't know zsh, but I remember in the past, some features have been 
aligned across shells, and it has proven especially helpful for clarity 
as an end-user when dealing with non-POSIX shell features

zsh also provide a nice feature to iterate both keys and values in a 
single loop:

for key value in "${(kv)assoc_array}"; do
    printf '%s -> %s\n' "$key" "$value"
done

which is quite nicer than doing same in bash:

for key in "${!assoc_array[@]}"; do
    value="${assoc_array[$key]}"
    printf '%s -> %s\n' "$key" "$value"
done


I'd love there would be more convergence when this is possible.
