Is it bad using linear/relative layouts inside a constraint layout?

Gamericious Blog :

I read something about layout nesting which some say is a bad practice but i have a xml layout where it makes me easier to group views with a linear layout and then constraint them too each other.

<android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:id="@+id/linearMarkStart"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toStartOf="@id/linearEndMark">

            <TextView
                android:id="@+id/mark_start"
                android:text="@string/start_label"
                android:textColor="#ffffffff"
                android:textSize="14sp"
                android:textStyle="bold"
                android:labelFor="@+id/starttext"
                android:clickable="true"
                android:focusable="true"
                android:gravity="center"
                android:layout_width="wrap_content"
                android:layout_height="31dip"/>

            <EditText
                android:id="@+id/starttext"
                android:textSize="16sp"
                android:textColor="@color/white"
                android:inputType="number|numberDecimal"
                android:layout_marginStart="10dip"
                android:layout_marginEnd="30dip"
                android:layout_width="70dip"
                android:layout_height="wrap_content"
                android:gravity="center" />
        </LinearLayout>

        <LinearLayout
            android:id="@+id/linearEndMark"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toEndOf="@id/linearMarkStart">

            <TextView
                android:id="@+id/mark_end"
                android:text="@string/end_label"
                android:textColor="#ffffffff"
                android:textSize="14sp"
                android:textStyle="bold"
                android:labelFor="@+id/endtext"
                android:clickable="true"
                android:focusable="true"
                android:gravity="center"
                android:layout_width="wrap_content"
                android:layout_height="31dip" />

            <EditText
                android:id="@+id/endtext"
                android:textSize="16sp"
                android:textColor="@color/white"
                android:inputType="number|numberDecimal"
                android:layout_width="70dip"
                android:layout_height="wrap_content"
                android:layout_marginStart="10dip"
                />

        </LinearLayout>
</ConstraintLayout>

What i have as output now by using 2 linearlayouts as childlayouts in constraintlayout and how i can achieve the same without those 2 linearlayouts because layout nesting is bad so it seems?

Henrique Becker :

For performance nested components/containers are better, but in some complex layouts they can make the code easy to understand and help to encapsulate code parts in separate reusable files.
