I don't think your problem is with HS Precision. They offer plenty of stocks without the large palm swell. The model 700 5r and Sendero SFII utilize stocks from HS with palm swells, but that's a Remington decision and has nothing to do with HS. I'm sure they'd be happy to supply Remington with whatever stock options they are willing to pay for.
On a personal note, for shooting off of a rest/bag or an improvised rest in the field, I quite like the wider palm swell. For a light weight mountain rifle I'm shooting off hand or maybe with a bipod, I could see not wanting it, but I'd probably also not have a heavy barrel in that rifle for weight savings. It's all about personal choices, unless you're Remington and choose to put the palmswell stocks on your rifle offerings. HS chooses to do what they are asked to do by their customer- they'd be happy to sell a non-palmswell stock to anyone who wants one.
