      What do you think of this idea:
      The board layout will be equipped with smd pads for a low drop voltage regulator.
      People who do not want the regulator simply short the pads with solder, and
      those who want to have stabilized voltage simply insert the smd regulator.

      That sounds very good. Do they want to see any legitimations ?

      CU,
