If you dig into the details, you will see that the TypeScript team take breaking changes very seriously and with consideration.

I think the TS team generally tries to minimize breaking changes from version to version and don't do so unless there is a good reason.

Of all the compile-to-languages, the one that strikes me as having the least merit is JSX. It's basically a ton of added complexity for the sake of what boils down to syntax. There are no real gains in terms of language semantics in JSX.

I agree that "it feels gross" is a bad reason. "not paving a bad cowpath" is a much better reason.

Because the code in question predates the introduction of the guideline and there is no other reason to be modifying that code.

We wondered - do voters carefully consider the political issues and then objectively study each candidate’s platform, or do they mainly go with from-the-gut “tribal” feelings? 

I would rather you vote against my position because you had an opposing view than vote with my position because you flipped a coin.

I believe that mere lists of "vote yes" or "vote no" are not very helpful except for sheep: it's important to know why one is urged to vote in any given direction.
