That is ofcourse an argument but I believe a bit of a non-argument at the 
same time in practice.

There's really not much point in pretending that non-git users are still 
first class citizens anyway; Linus' own suggestion of using git-blame would 
tie things to git as well, as do for example frequent requests to bisect a 
problem. I moreover feel there's absolutely nothing wrong with that, given 
that there's nothing wrong with git.

It's the kernel's source code management tool, is included out of the box in 
most distributions nowadays and is GPLd meaning that the tool (itself) won't 
keep anyone from exporting data from it and importing it into something else 
if someone cares to. Also, I never managed to stay un-annoyed at source code 
management tools long enough to understand why I wanted to use them but have 
been using git for months now so as far as I am concerned, it appears to 
even be a good tool.

But, well, anyways, I did look at a git repo a bit but will unfortunately 
not be able to follow up the proposal with actual (good) code in a sensible 
timeframe, let alone "quickly", which means I was hoping others would agree. 
I believe these properties make for an elegant setup with many possible uses 
including the maintainers information, but if you disagree I guess I'm going 
to shelve it...

Yes, not unlike the current git move "meta-diffs" ...

The important reason for wiring this into git directly would be keeping the 
meta-data in sync with the data it refers to in an automated fashion. With 
manual intervention, there's much more opportunity for things to grow stale.

In practice, it may not be a huge problem. It certainly is with the current 
MAINTAINERS file but if one does finer-grained data around the tree, that 
will probably help.

It's also not a now or never thing fortunately. If git does ever grow these 
properties, the issue can be revisited, perhaps at that time both with the 
experience of what the finer-grained in-tree solution did not solve and even 
fewer people around that care about not making git even more of an intrinsic 
part of development.
