Only benefit I see to this is retaining the stock snail with a little added power for whatever reason you wanted to push 300 with all the supporting mods and "not" upgrade your turbo. Which I feel would be a very small portion of people. You are either like me, lightly modified, stock, with the exception of a tune, plugs, bpv, and filter. I want a low cost, added performance, daily. Or you go full bolt on, fmic, intake, tune, bov, charge pipes, dp, exhaust, mounts, ect. I feel the that person is just going big turbo next, and someone like me won't spend the money.
Only reason I see is if someone was full bolt on and wanted to keep a stock appearance turbo to squeeze by some warranty work without having to swap a turbo, and visually still look stock. But if they're a good tech they will know when someone has been in there either way. Or wanted a sleeper type setup. Back in my DSM days on my 2G Talon (15 years ago) I ran a Big T28 Garret, which was a ported, bigger wheel version of the stock T28. From the outside it looked stock until you pulled the intake tube off you could see the port and larger wheel. But that quickly needed a larger FMIC and sleeper went out the window. That's when it was cool to be a sleeper and average street horsepower was lower then what most cars put out stock these days lol. You can't be a fast "sleeper" anymore lol. If you're considered fast, people will know.
