Are views safe to have other people editing them?

Hi. I am using gitlab.

But if this project gets of the ground, hundreds of frontenders can work within the same repo.

I actually saw someone posting a similar question.
The suggestion there was to create an API which handles the controllers and models.
And have the frontenders use another detached environment for their code.

This requires some rebuilding, but I think it's the safest way, don't you think?
