Should have

• Remove script runner. Maybe keep installation lifecycle.
• Remove integrity checking,
• Remove --watch flag.
• Install from standard library first when using --mod flag, if can't find the name in the standard library then check in third-party libraries.
• Add a way to install a third-party library with the same name as the standard.
• Make --mod as default by using install subcommand.
• Use deno.json(c) file as default importMap.

Maybe

• Subcommand to parse npm scripts to deno tasks.
• Subcommand to parse npm depedencies to deno importMap.

Probably before v2

• Support to npm: packages.
• Support to node: packages.
• Support to deno.json(c) importMap.
