I share your sentiment that it could drive away candidates and from time to time we reevaluate the costs and benefits of switching to a mainstream framework.

Concerning maintainability I am really happy with our codebase. Strict rules and tooling help us keeping a clean state. You can write non maintainable code with any mainstream framework or even confuse a new developer when writing idiomatic code for this framework is not well defined.
