No you don't. 

You could just as well claim that you don't want people to write
code in other languages because you then would need to be able
to decipher code written in that language.

Your day-to-day requirements are a contract between you and your
employer or between you and your clients. That you don't want
mental gymnastics as part of that, shouldn't be a concern for
how the language develops.
