I'd prefer not to, at this point. Various hierarchical group
proposals are playing with other meanings of leading dots and
slashes, and I don't want to close that possibility for
a rarely-used shortcut. [[{.$Group}/here]] isn't that onerous
for the few times it'll be used (and it's also more explicit).

Group config pages apply only when the currently browsed
page is in the group. Settings in a group config has no effect
when a page is accessed from another group (which is why group
configs cannot be used to set passwords).

[[!Category]] is already fully qualified, so it's
not an issue. Entries in Group.SideBar tend to be
seen only in the current group anyway, so that's pretty
safe. (How often does a page include a sidebar page from
another group?) The links in Site.SideBar tend to have to
be fully qualified anyway. The main places it would cause
issues in in things like:
[[recent changes]]
--> [[{.$Group}/recent changes]]
[[{$FullName}?action=edit | Edit page]]
--> [[{.FullName}?action=edit | Edit page]]

Good observation.

I would, because I think an author's natural inclination
is to think that {$Name} in a GroupHeader refers to the
name of the currently browsed page, and not "GroupHeader".
Most people don't realize that GroupHeader is implemented
by using (:include:). :-)

Only if the borrowed page makes use of {$var} or [[link]].
Not common, I don't think.

I'm not sure there's a lot of docs that have {$var}
markup in them that depends on it being absolute as
opposed to relative. Some skin configuration pages
might, though.
