Hamilton was workshopped for a very long time and then had a long Off Broadway run at The Public Theatre where additional changes were made. A huge amount of money went into it because of the trust that Lin Manuel had generated with previous work.

Spiderman was in tech for over a year (beta testing) because the damned flying didn't work. Then they radically changed the script because it hadn't been workshopped, and it was still terrible.

I would encourage you to work on a theatrical production some time. I think you'll find a lot of familiar difficulties, including insane schedules, incompetent management, project bloat, abuse and burnout.
