37signals did basically this with same number of staff you can read about it on their blog. It’s not rocket science
It’s not like your description is ridiculously reductive, or like 37 signals/dhh have a history of attention seeking behavior that might drive them to make technical decisions on the basis of PR value. Never!
This is not a question of why they did it (although they pretty clearly expand on it in those posts and everyone who didn’t flunk middleschool math can do the same with their setup) but question of can you do it. And the answer is pretty clearly - yes. But ofc you won’t, and not because of technical reasons either.
