Maybe. Here's what they say in the readme of the project people are complaining about:

The password manager SDK is not intended for public use and is not supported by Bitwarden at this stage. It is solely intended to centralize the business logic and to provide a single source of truth for the internal applications. As the SDK evolves into a more stable and feature complete state we will re-evaluate the possibility of publishing stable bindings for the public. The password manager interface is unstable and will change without warning.

There are two ways to take this:

• this is temporary as they're refactoring code to reduce duplication across clients
• refactoring is an excuse to create fully proprietary clients going forward

Until I see evidence of the latter, I'll stick with the project, but I'll be more consistent about creating backups so I can switch easily if I need to.
