Is the project abandoned? Why don't devs acknowledge important issues?

I am struggling to configure the project generated with sequelize-cli to use sqlite instead of MySQL. https://github.com/sequelize/cli/issues/1528 (there is no option to select dialect) There are other issues such as sequelize-cli not generating TypeScript files. https://github.com/sequelize/cli/issues/1436 (there is no option for that). sequelize-cli also generates files in CommonJS syntax instead of ES6 syntax (import x from y, export default, export). https://github.com/sequelize/cli/issues/960 (there is no option for that). People had to change the syntax manually. Last update of sequelize-cli was in 2023.
