Forum:SUBST or not on talk pages?

I see that on talk pages, things like welcome messages are SUBST:ed. I think we shouldn't SUBST: them.
 * It is harder to remove hard table syntax for new users than to remove a friendly template.
 * It is less user-friendly to edit talk pages with a big piece of code.
 * SUBST:ed templates can't be kept up to date, for example, if wikia shrinks the layout again, old talk pages' layout will be obstructed, and only layout of new talk pages will be correct.
