Would it be
especially complicated to add the namespace=? parameter to the
"What links here?" mechanism?
I would be quite happy to add it to the URL manually at first, but this
would be most useful ploughing through huge lists of links trying to make
out whether something is actually being linked to meaningfully.
Did I miss an answer to this question I wrote back in October?
There hasn't been a reply. But the answer to your question is "no, it
wouldn't be especially complicated", especially since you stress that
you don't need a UI for it.
To find someone to code it may be the harder part. Last time I did
something like this it was reverted with a snide remark from Brion, so
I'm not doing this again.
