The cloudbase ecosystem is realy awesome.
But as a developer who places a lot of importance on pkg size, I found many of your published pkgs to be extremely large, this is probably because you included the unnecessary source code in it, which may not be the best practice
Hope you guys can fix them in time(may or may not like this PR)

BTW, Happy 🐄 Year!
