Sencha 6.5, where classic and modern folders while create new packages - extjs

Question

I was trying sencha 6.5, I've created a package using
sencha generate package DemoPkg
This has created a package for me, but I do not find directories for classic and modern inside it. Did anyone faced this issue? Any suggestion or help on this will be much appreciated.
As per sencha guide the structure of package should have following structure,
packages/
local/
foo/ # Top-level folder for the package
.sencha/
package/
sencha.cfg # Sencha Cmd configuration for this package
build-impl.xml # Generated build script for package
plugin.xml # Sencha Cmd plugin for this package
codegen.json # Data to support 3-way merge in code generator
classic/ # Classic toolkit-specific src code
examples/ # Example applications demonstrating the package
licenses/ # License agreement
modern/ # Modern toolkit-specific src code
overrides/ # Folder for automatically activated overrides
resources/ # Static resources (typically has images folder)
sass/ # Container for styling code
etc/ # General, non-component oriented styling
example/ # - internal use
src/ # Style rules named by component
var/ # Variables and mixins named by component
src/ # Folder for normal JavaScript code
build.xml # Build script (called by `sencha package build`)
package.json # Package descriptor
Readme.md # High-level information about this package

Sencha CMD will not generate the toolkit folders as mentioned in the docx and there is no options to do it, only we can mention the toolkit type for theme package. so we need to manually create the folders similar to universal app(both classic & modern) and update the package.json with path ${toolkit.name} like below
"resources": [
{
"path": "resources"
},
{
"path": "${toolkit.name}/resources"
}
],
"sass": {
"namespace": "UniversalPkg",
"etc": [
"${package.dir}/sass/etc/all.scss",
"${package.dir}/${toolkit.name}/sass/etc/all.scss"
],
"var": [
"${package.dir}/sass/var/all.scss",
"${package.dir}/sass/var",
"${package.dir}/${toolkit.name}/sass/var/all.scss",
"${package.dir}/${toolkit.name}/sass/var"
],
"src": [
"${package.dir}/sass/src",
"${package.dir}/${toolkit.name}/sass/src"
]
},
"classpath": [
"${package.dir}/src",
"${package.dir}/${toolkit.name}/src"
],
"overrides": [
"${package.dir}/overrides",
"${package.dir}/${toolkit.name}/overrides"
],
