Might be better to drill next to the vias and bend the wire over, this
way the drill won't rip the copper off.
Generally i'd rather not push the limits of reliable and practical
manufacturing so far, if the goal just was a useful PCB. If it's also
a study into how fine one might go that's another issue.
