What's the recommendation for creating development schemas at a large org?

[olly-writes-code]

The dbt docs recommend that organizations create a development schema for each dbt developer.

If you have multiple dbt users writing code, it often makes sense for each user to have their own development environment. A pattern we've found useful is to set your dev target schema to be dbt_{username}. User credentials should also differ across targets so that each dbt user is using their own data warehouse user.

This might be okay at a small company, but at a larger company (50 dbt devs) this can lead to an explosion of schemas. How are other organizations thinking about this? What does the dbt team recommend?
