Who gets to decide anything? We might as well not speak at all, lest we share spme opinion that's counter to what some other person believes - and some people will believe anything, even that the earth is flat or that crocs are stylish.

Back in real life, however, a Python programming environment limited to "just what it offers in the box" might make some "happy", but it's very easy to argue that it's not serious.

For the person that decides to use it, it is serious enough.

Do you mean the "real life" where UNIX CLI stuff gets cargo culted as the only way a developer works?
