Did you forget /s at the end of this?
I work at big tech and the number of bad deploys and reverts I've seen go out due to getting types wrong is in the hundreds. Increased type safety would catch 99% of the reverts I've seen.
Also have fun depending on libraries 10 years old as no one likes upgrades over fear of renames.
Ops type here, I’ve got multiple stories where devs have screwed up with typing and it’s caused downstream problems.
Never has been an issue in practice...
