There's all of the new features that've been suggested for our current hush, many by Sean, for which the reply has been "our hush is old, it should be updated!". And you didn't address my point, taking code from another project requires dedicated maintenance to keep it up to date and we do have a lot of in-tree examples right now of where that lack of dedicated maintenance is a problem. > > But I > > really think we want a shell environment that is not actively adding new > > features is a good thing, for the default.

Honestly, adding new features to the CLI (which is NOT the same as adding new commands, or enhancing existing commands) is very low on my priority list. We need to get the Kconfig migration done. We need to get DM migration done (which will help with the Kconfig one by showing hardware no one cares for anymore, and reducing symbols). We need to make adding new hardware easier. We need to get DTS files in-sync more often. There are very important developer use cases for a more flexible CLI interpreter. But the main use case is still "boot the (redundant) OS ASAP". So, what is my priority on this series right here? Well, a developer has posted a series. They believe it's useful and addressing a long-standing problem. They want feedback. I'm trying to provide feedback as it's to a general area of the codebase. -- Tom
