This is very important. I personally like old technologies and languages where the designers considered users who had limited technical skills, and most importantly, assumed that those users had no interest or need to improve their technical skills. Removing the assumption that users are willing to increase their technical sophistication forces a designer to think more about what they're designing. Looking at older languages is interesting - for all their warts, they do feel more intentional in their design than modern things that have a clear developer-centric mindset baked in.
It's similar to the discussions around COBOL back in the day. What's interesting is that the primary "end user" language is Excel formulas. Who would have thought a declaratory relational language with matrices would "win" that battle.
Any arguments that "users will write their own" languages are basically flawed. Users want results, if there's no alternative, they'll do it themselves, in the simplest, but probably most inefficient way possible.
