you use dash as soon as a script doesnt run as your user, if you write
shell scripts it is good practice to use POSIX compliant code ...

indeed if its only scripts you run when being logged in so that your
defined user shell is used, there is no prob with writing it for bash
only.

and indeed you can force usage of bash (with all its disadvantages) by
setting
#!/bin/bash 
in your script.
