Right, but the user should be able to "throw money" at a problem if
that's what they need, either spending money to purchase a commercial
autorouter, or paying someone to write a free one.  Thus, it would be
good to be able to say "PCB supports the industry standard FOO
autorouter interface" and let the user decide how much they want to
spend on autorouting.
