Comment (by Lwangaman):

 Perhaps a way to transition this to new logic could be to add the
 possibility of using "options" instead of "choices" in a transition phase,
 explaining the difference in the documentation and inviting to transition
 to the new style "options" instead of "choices". Then it could be handled
 something like this:

 {{{#!php
 <?php
 case 'select':
         if ( empty( $this->choices ) && empty( $this->options ) ) {
                 return;
         }
         ?>
         <?php if ( ! empty( $this->label ) ) : ?>
                 <label for="<?php echo esc_attr( $input_id ); ?>" class
 ="customize-control-title"><?php echo esc_html( $this->label ); ?></label>
         <?php endif; ?>
         <?php if ( ! empty( $this->description ) ) : ?>
                 <span id="<?php echo esc_attr( $description_id ); ?>"
 class="description customize-control-description"><?php echo
 $this->description; ?></span>
         <?php endif; ?>


         <select id="<?php echo esc_attr( $input_id ); ?>" <?php echo
 $describedby_attr; ?> <?php $this->link(); ?>>
                 <?php
                 if( ! empty( $this->choices ) ){
                         foreach ( $this->choices as $value => $label ) {
                                 echo '<option value="' . esc_attr( $value
 ) . '"' . selected( $this->value(), $value, false ) . '>' . $label .
 '</option>';
                         }
                 }
                 else if( ! empty( $this->options ) ){
                         foreach ( $this->options as $label => $value ) {
                                 if(is_array($value)){
                                         echo '<optgroup label="' .
 esc_attr( $label ) . '">';
                                         foreach( $value as $label =>
 $value ){
                                                 echo '<option value="' .
 esc_attr( $value ) . '"' . selected( $this->value(), $value, false ) . '>'
 . $label . '</option>';
                                         }
                                         echo '</optgroup>';
                                 }
                                 else{
                                         echo '<option value="' . esc_attr(
 $value ) . '"' . selected( $this->value(), $value, false ) . '>' . $label
 . '</option>';
                                 }
                         }
                 }
                 ?>
         </select>

 }}}
