I said that considering the opacity was replacing the ability to
customize the placeholder style. I probably misunderstood the idea.

Actually, I've tested with 0.6 opacity which is not the best value. On
WebKit the default color is darkgrey, if I recall correctly, and we are
able to get something looking more or less like darkgrey with opacity
values between 0.3 and 0.4. However, it is not the exact same style and
I prefer the darkgrey's one.

Here is a small HTML sample to test:
<html>
  <style>
    input.test::-webkit-input-placeholder { opacity: 0.35; }
    input.test, input.test::-webkit-input-placeholder { color: black; }
  </style>
  <body>
    <input placeholder="placeholder">
    <input class="test" placeholder="placeholder">
  </body>
</html>

Anyway, I am not a website designer so my point of view about the style
quality is not really important and as you said, the additional benefit
is important.
