I have. Many times. Burned many hours over it.
And there's a trivial demonstration for why it's useless to even pretend to attempt a colorimetric workflow with Adobe products. To the best of my knowledge, not a single vendor sells _any_ product for building DNG profiles with anything other than a 24-patch ColorChecker, and those products that support a ColorChecker don't let you provide your own measurements for the chart nor SPD information for the actual illuminant the chart is photographed under. And, even if you _do_ somehow manage to create a perfect DNG profile, you're not even theoretically going to get colorimetric accuracy from it unless you light the scene with a perfect D50 simulator -- something that doesn't actually physically exist, of course.
Each bullet point in that paragraph is a showstopper, incidentally. And it's only barely scratching the surface.
Adobe makes great products for certain types of artistry. But attempting to use Adobe products for anything where colorimetric accuracy is an essential part of the workflow is as insane as attempting to use a Lamborghini to sow crops or racing a farm tractor in Le Mans. Yes, both a Lamborghini and a farm tractor have four wheels and similar operator controls. But only a fool would use the one where the other is called for.
