There are many of those. For example, the 1-series bodies let you apply up to a stop of 'background' EC and FEC, which they term AE and FE microadjustment and can be set in 1/8-EV increments.
Do keep in mind that there is a cost associated with implementing any function, even in software. On the surface, it seems like it should be a simple matter to take a feature in one camera and implement it in another, and that doing so should be 'free'. But that's not the case.
As a counterexample, when the 1D X came out there was a bug in the AF Microajustment such that the lens-specific values were not stored...but only if the option orientation-linked AF point was selected. Both features were available on previous cameras, but when implemented on the 1D X one setting borked the other. It took me and another forum member to get to the bottom of it. I found the AFMA bug, but not the association with the orientation-linked AF point, the latter enabled Canon to reproduce the issue and led to them developing a firmware update to fix it. So two 'free' features from previous cameras...weren't so free.
