With all due respect, you don't know what you're talking about. If the engineers you know do that, you don't know good engineers.
edit: I can't reply to tekla's comment, so I'm editing here. It's frustrating on Hacker News for an expert - like myself, who has sat in on dozens of mastering sessions - to be disputed by someone who "knows some people." I'll clarify further. Do some engineers use the same mixes for vinyl as they do for digital? Sure. They're not good engineers. Or the customer hasn't paid enough (it's usually about $60-$100 per song to master per format). Vinyl is a drastically different medium than digital - of course - and any decent engineer will 100% mix differently and accordingly. If there are artists reading this and your engineer is using the same mix, fire them. You're paying a lot to press to vinyl so do the followthrough and get vinyl-specific mastering.
Here's a good article from an engineer I have worked with many times on why mastering for vinyl is different:
