Not really unpopular. That said, while flour (kind of the backbone of most baking recipes) is prone to being inaccurate when measured by volume, there are a lot of ingredients which do not have this problem and are not as sensitive to being measured wrong. If a cookie recipe calls for a quarter cup of chocolate chips that's probably fine. I think a lot of people don't have a scale sensitive enough to measure a half gram of yeast, either.
Depending upon the country, salt and sugar can also have different textures and grain sizes that can cause complications. I say this as I convert my US family recipes here in Japan.
