@darius I suppose in this case it's "user experience customizability, including for accessibility" and "developer time and task-complexity, especially for the task of ensuring security" that are the competing access needs.

(And like many Competing Access Needs situations, some people have both needs! There are undoubtedly disabled dissidents with various disabilities who both need to be able to use tools, but also need those whatever tools they use to be rock-solid securitywise. And that's even leaving aside the "developers are people too with a finite amount of effort they can safely and confidently put in".)
