This is common in open-source. If you come to the mailing list talking
about a feature, without a patch, the maintainers let you know how
likely they are to want to write or maintain that feature. You haven't
given them a patch they could trivially merge in, so it reads as if
you're asking them to write the feature. Why write a feature that they
would never use?

Writing it yourself is one way to get a feature included that the
maintainers wouldn't use themselves. But you have to realize that
they're still thinking about having to maintain that feature. Every
new feature adds work to them, making sure that their future work does
not break it. There will be some features that are just deemed not
worth that effort by the people that control the official repository.
This is why forking is sometimes (rarely, but sometimes) acceptable.

Not only that, it's a differentiating feature of Git and it sets it apart from other SCMs, in a good way. We could mindlessly homogenize to be more like other systems, or less "surprising" for users coming from other systems, but we'd be throwing away something valuable in the process.

Nothing is being forced down anyones throat by Git. Git doesn't
somehow force you to use Git from here into eternity. You state later
that you *have* to use many different systems. But it's not Git that
forces you to do so.

This sounds to me like you should try to simplify your setup. I know
that sometime it's not possible, but you're fighting an unwinnable
battle. If you're truly using that many different systems with
overlapping functionality you are destined to be confused. Period.
Most SCMs now do a good job of migrating data and in some cases (git
svn, for instance) sharing data on an ongoing basis. There are also
tools around that handle multiple SCMs behind one consistent
interface.

I'm not one of the maintainers, so maybe I'm speaking out of turn, but
as I pointed out above, they are losing something for letting in
options. They will have entered into an implied contract with their
users to keep that feature working in the future, putting a burden on
future development efforts. This is not without cost.
