Yes. But: Only if it makes the code better.
I think that “understandability engineering” is just as important as “software engineering”. Maybe more so. After all, code that we understand has a better chance of working correctly than code that follows all paradigms but once the developer is gone nobody is able to maintain. I.e. worry less about idiomatic programming and write more understandable code. Swift is getting - well maybe it’s past already - the point where an experienced programmer can write code that no newbie has even a chance of understanding. If code blocks help in breaking this trend, go for it.
