Comment (by afercia):

 > it could be too soon to remove opacity: 1 on the front end. About 18% of
 Firefox users have a version before the browser's style change.

 Sure. The WordPress admin supports the last two versions of the major
 browsers. The Themes support is unclear to me. Anyways, there's no need to
 rush.

 Re: the color, I guess it should be a color that fits with the theme's
 color palette so that I'm not sure all themes can use the same color.
 Also, some themes use a light gray background color for the inputs (for
 example: Twenty Sixteen). In these cases the placeholder text color should
 still provide a sufficient color contrast with that specific background
 color.
