What difference if I move `/imports/startup` to `/app/client, /app/server`

I would like to move /import/startup to /app/client, /app/server.
Bc I don’t want to import any file any time.
What difference?

The difference is that anything in /import will not be automatically loaded at run time and will need to be explicitly imported. That being said switching your app away from imports sounds like total lunacy to me…

But anything in import/startup/.. is auto loaded in /app/client, /app/server too.
