That sounds great until it bites you in the ass really hard. In general, you want to catch unintended behavior as early as possible.

You want to, but they don’t. Those people just want to get stuff done, as opposed to a language like Haskell or stricter where you’ll never be able to get old code to run because newer compilers print errors that take a week to understand. There’s some old Yegge articles about this…

PHP converting between strings and numbers is usually a mistake, but the one data structure doing everything (array and dict) is nice enough.
