Whilst this may turn it into a redlink, a more dangerous result is if
[[Help:Bar]] already exists so the destination changes and nobody spots it.
I'm not really convinced this would be a serious problem, though. For
the kinds of applications this feature would most likely be used (such
as the "micro-wikis" this thread started from), I wouldn't expect
cross-namespace moves to be common at all, and those who did them would
presumably know what to expect. Compare the situation with the current
transwiki process, where the same problem already occurs and is handled
routinely.
Of course, if someone were to feel like implementing it, a "fix link
targets" option for cross-namespace moves would be a nice cherry on top
of this feature. Could be useful for transwikiing as well, and it might
even be possible to make it fix relative subpage links too.
