This is a case of "depends on the project".

For very small projects, code may be the main bottleneck. Just to write the code is what takes most of the time. Adding code faster can accelerate development.

For larger projects, design, integration, testing, feature discovery, architecture, bug fixing, etc. takes most of the time. Adding code faster may slow down development and create conflicts between teams.

Discussing without a common context makes no sense in this situation.

So, depending on your industry and the size of the projects that you have worked on one thing or the other may be true.
