I think having a lingua franca have way more advantages than drawbacks.
As a spanish native speaker, I know is easier for me that for someone whose first language doesn't come from latin, but is really not much of a hassle.
Even coming from one of the most used languages in the world (and having a just enough english level), is very rare that I search of read something programming related in other language than english.
