bluebird

The README strongly recommends using native promises instead, indicating Bluebird is no longer the optimal choice for modern development and may be seen as deprecated.

Adds unnecessary size and complexity to projects that could rely on native promises, leading to larger bundles and potential performance hits in modern environments.

Introduces non-standard methods like cancellation and progress tracking that require additional learning and can create lock-in or migration challenges.

As native promises have matured and incorporated many Bluebird features, its utility has diminished, with limited active development focused on new innovations.
