Been a while since I looked at this but it still seems to work for me in
3.14.0.
Corresponding <Permission> elements are generated in files.wxs:

        <DirectoryRef Id="CM_DP_empty_directory_with_property">
            <Component Id="CM_C_EMPTY_CM_DP_empty_directory_with_property"
Guid="3D2461E6-022E-462E-BE97-3DE14D7DFEBE">
                <CreateFolder>
                    <Permission User="Everyone" GenericRead="yes"
GenericWrite="yes" CreateFile="yes"/>
                </CreateFolder>
            </Component>
        </DirectoryRef>

        <DirectoryRef Id="CM_DP_non_empty_directory_with_property">
            <Component
Id="CM_C_EMPTY_CM_DP_non_empty_directory_with_property"
Guid="20B69238-5353-4C30-A001-3A106A0B1737">
                <CreateFolder>
                    <Permission User="Everyone" GenericRead="yes"
GenericWrite="yes" CreateFile="yes"/>
                </CreateFolder>
            </Component>
        </DirectoryRef>
