I think this is one of those cases where it works, but there is something out there that is just as good as it if not better and that may cost less to use. Unless you got a lot of 2400 for free. Or just want to keep a minimum number of powders on the shelf to suit most of your needs and buy bigger containers of a particular favorite for economy. I certainly understand that concept since I use one fairly non-standard powder for nearly all of my general purpose handgun range/practice/cowboy action loads. It worked best for many of my load applications, and as good as or better than more traditional powders after some load development. If you shoot a whole lot of 44 or 357 Mag, hotter 44 Special, 38-44HV, etc. and prefer 2400 for that so you have a lot of it around, then it makes sense that you may want to use it for occasional 38SP.
