As for #1, what I dislike in conversion during save is the fact
that _editing afterwards_ is still difficult (and I truly see no
gain in making this sort of pre-processing - it could be done
in runtime just as well).
The gain is that the author has at edit time full control over where the
link points to. With runtime lookup a link might change because a certain
term was added to a certain namespace.
