Oh, no, I mean *tracked* symlinks in one repo, linking to *tracked*
files in *another* repo. I guess I just totally misunderstood your
original message.
Regarding dotfiles, I'm doing pretty much the same thing, moving stray
dotfiles to "$XDG_CONFIG_HOME/$APP/$FN" (maintaining a separate repo per
application) and using Joey Hess' mr(1) [1] with the 'fixups' parameter,
automatically calling e.g. :
$ ln -s -v ${XDG_CONFIG_HOME}/git/gitconfig ${HOME}/.gitconfig"
on checkout/fetch/etc...
(BTW git complies with the XDG Basedir Spec as of v1.7.12 [2],
so one less homedir polluter to babysit!)

Now I get it :)

If there are in fact people who consciously use some VCS other than git
(or SVN through git), uniformity is the least of their concerns :)

Hmm, AFAIK, its default value is 'ask, so if it's anything other that
that, it means someone actively made that choice, no matter the reason.
Second-guessing that just wouldn't be polite.
IMO, the least obtrusive way would be adding `vc-follow-symlinks' to the
'magit customization group [3], thus making users aware of its existence
and its relevance to Magit, and the rest is up to them.

An obscure corner case like inter-repo symlinks? :D
