At the time of the Bloodstained kickstarter, Igarashi had no ties to Konami. He quit, likely because Konami didn't want to make games anymore.
Same for Inafune and MN9. He quit Capcom because he was sick of fighting to try and get something to happen. His bosses wouldn't let him do anything nice.
Shenmue DID strike me as rather dubious.
I do feel obliged to note that the game market in general was very different when Bloodstained's campaign started. The Wii U and Vita were viewed as viable gaming platforms, for one.
"Indie" games were looked down on, and the console manufacturers were starting to care about them, but they were very much second-class citizens. This is less true now, though the mass-market release was never going to be a sixty-dollar game. Essentially, everyone that "preordered" on Kickstarter placed a forty-dollar preorder and a twenty dollar(or MUCH more, and I salute you three crazy fools that pledged ten grand for a night on the town with Iga) contribution to the development fund.
At the time of the Kickstarter, there was never any chance of Bloodstained ever getting a digital disk release. It was going to be download-only outside of the kickstarter. It turns out a lot of things happen when you have five and a half million dollars in outside funding that won't otherwise. (It was also going to be out two years ago, because the goal was a simpler game.)
If you want to get mad about exclusive content, consider the folks that pledged for the limited autographed Amano print, They more than tripled the number of autographed prints available after the first ten "sold out". That struck me as dubious for something explicitly advertised as very limited availability
I pledged at the hundred-dollar level, incidentally. Aside from backer-exclusive packaging, demo builds, "free" copies of Ritual of the Moon and the swordwhip expansion pack, I also get a keychain, pin, soundtrack CD, "retro cheatbook", and my name in the credits. Those physical objects are never going to be available to non-backers, not even through piracy.
I would have been more hesitant to chip in anything, and certainly not as much as I did, were it not for the talent associated with the project.
