I have this weakness that when I read about some old, obsolete technique and I have the means to do it, I want to try it out. I did a clone of Pilsner Urquell a few years ago using the original process - undermodified malt, 4 hour quadruple decoction, 4 hour boil. I've played around with Turbid mashing, and one time helped brew a Sahti in a wood-fired sauna using a hollowed-out log (kuurna) lined with straw and juniper twigs as a sparge vessel.
It's about the experience, more than the results. There is a reason these techniques are no longer widely used. But by doing them, it does give me a much better feel for what works and what doesn't, which gives me more options when I decide to do something that is outside the box.
So I would encourage you to give it a try, but don't expect to adopt it for typical use. Simply adding DME is MUCH easier and faster.
Still looking forward to someday finding a wooden tub I can use for doing a stone brew (boil using red hot rocks dropped into the wort as a heat source).
