Perhaps mention the benefit of not hosting your code on e.g., your lab website

Lots of code/software is only on scientists lab websites. If those go down the software could be gone, etc.

There's an entire section on it: 3. Backup and failsafe against data loss

Collecting new data and developing methods for analysis are often expensive endeavors requiring significant amounts of grant funding. Therefore protecting such valuable products from loss or theft is paramount. A recent study found that a vast majority of data and code are stored on lab computers or web servers both of which are prone to failure and often become inaccessible after a certain length of time. One survey found that only 72% of studies of 1000 surveyed still had data that were accessible [@Schultheiss2011; @Wren2004]. Hosting data and code publicly not only ensures protection against loss but also increases visibility for research efforts and provides opportunities for collaboration and early review [@Prlic2012b].

Does that seem sufficient?
