Thinking about SQL which I use quite a lot (and the only real declarative programming I do):

1. I would not say that SQL is harder to debug than imperative code. I have also noticed that I get less bugs and they take less time to solve when I push as much as possible to SQL. Usually something either works properly or it doesn't. I personally find SQL is one of the few languages where reading the code is easier than writing it.

2: Database optimizations must be some of the most well known ways to improve performance in the tech field.

3: SQL syntax isn't great (I wouldn't say it is terrible either).
