I do - the advantages are almost exclusively for lead, and even then they aren't a huge advantage unless you're trying to develop your lead playing, or you are trying to play lead stuff that is very, very demanding.
The entire point of a scalloped board is to train you not to press the frets so hard, because you literally physically cannot shred past stepdad speed when you're monkey gripping each note you fret.
This is most helpful/the biggest issue with the upper register; hence why many guitars only have the top 5-10 frets scalloped. But scalloping the entire board is a good solution if you want to force yourself to constantly be practicing and utilizing "best practice" as far as the amount of pressure you use to fret each note.
That's why I've said it's a great training tool. I owned and used an yngwie strat at a really important developmental period of my guitar playing where I couldn't figure out why I couldnt get my left hand any faster, and it was really, really helpful.
If you don't want to play leads or don't care about them, there really isn't any huge point in it. Indeed, as yngwie says, most of the reason he did it originally is because all the major companies used pretty low slung frets to begin with - there are diminishing returns if you have huge, modern, jumbo frets.
