Does that really happen for you?

The workaround is to use ugly, likely to be unique target names - or
address the enhancement request this discussion came from and depend
on "imported.foo" for your newly introduced meant-to-be-private target
"foo".

When you completely want to replace a target that is, true.

Another related problem I have is that you can't add something to the
beginning of a target easily.  You can add someting to the end of
"foo" by writing your own "foo" that depends on "imported.foo", but if
you want to add something at the start your imported build file has to
be designed for it.  Which means pseudo-targets that are used as
interception points only.

Once we can import URLs, you can have a solution for this, at least
for "network connected" development.
