Is it safe and sensible to link sh to dash?

In theory, dash should be faster than bash. So I was wondering if you should link sh to dash (instead of bash). Can this cause problems with existing scripts under Slackware?
I also noticed that /bin/sh is a link to bash, but bash is started in a certain mode: The prompt is sh-5.1 instead of bash-5.1. So is this already a script-optimized version of bash? If so, does it even make sense to link sh to dash or is this optimized version of bash just as fast?
