Where I live in Australia, small developers would be the biggest opponents of things that limit their opportunities to subdivide and build more densely - parking minimums, setbacks, frontage minimums, shadowing, sight-lines and so on. (I don't know what "offset" is in US real estate lingo.) The limitations are largely NIMBYism. There's a block of six units in my short one-block street of otherwise detached single-family dwellings, and the elderly neighbours here talk about how they wished they'd objected to its building decades ago because it changed the character of the street. It's all tension between "what is best for me and the street as it was when I bought into it" and "what is best for us all collectively". Building here is slightly outpacing population, but it is too financially attractive to buy second and third properties as investments, and it is politically risky to tackle that.
