I often try to find new ways to do things. Maybe 9 out of 10 times my new
way is not better. But for that 1 in 10, the "art" is advanced. So for me it
is worth the effort.

There used to be a small tool that was used to create an island around a
drill hole. it was effectively a micro sized hole saw. The technique was
to drill holes in copper clad where you wanted them, isolate this hole with
the tool (as needed) and then bridge from island to island with the parts.
You've probably seen that one and decided it's not what you want. A similar
approach would be to use a dremel as a router, make a small template that is
large enough to manage, and has various patterns in it, then use the dremel
as a router to remove the copper around that island. Never seen anyone do
this, but it would have an advantage that you could make templates of your
favorite circuits with a sheet of scrap aluminum, isolate as needed, (no
through holes required) and have essentially the same layout each time.
you'd have to be somewhat careful with the depth setting, but a small
fixture could be made to allow you fast setup.
