A year ago I could not write a JOIN. Formulário now writes to your own database, which forced me to learn the thing I was abstracting. Report:
What changed: I debug customer issues 10x faster (I can read the query log now), my "impossible" list shrank (half of it was just SQL), and I stopped fearing migrations (still respect them, thanks hoshi).
What did not change: customers do not care what powers it. "Now with real SQL" converted zero trials. "Your data stays in your database" converted plenty. Sell the property, not the technology.
No-code got me here. SQL keeps me here. Both were correct at the time.
