Batching a bunch of breaking changes together so they all come at once and you only have to deal with them once is fine.

What I am asking is, why did there even need to be a breaking change in the case of the function discussed in the article? No functionality changed; the Python standard library function was identical to the former Flask function. So why couldn't the Python standard library function have been imported into the Flask namespace to replace the former Flask function? Why force every user to do that manually?
