svnwcsub.py does not work across different SVN trees
It looks like svnwcsub.py is not always able to update the workspace
if the source URL is updated in the configuration file.
I am seeing an error of the form:
svn: E195012: Path '/www/ace.apache.org' does not share common version
control ancestry with the requested switch location. Use
--ignore-ancestry to disable this check.
svn: E195012: 'https://svn-master.apache.org/repos/infra/sites/ace'
shares no common ancestry with '/www/ace.apache.org
Is there any reason why the svn switch command does not include the
suggested option?
Seems to me it ought to be possible to replace the checkout with a
different SVN repo without needing to manually remove the existing
checkout.
Sebb.

If you want to propose that that flag be added, the onus is on you to
make the case for adding it, not on everyone else for making the case
against adding it. You've been around long enough to know this.

How would the code tell the two cases apart? What are the proposed new
semantics?

This is not about a new deployment, but about changing the URL for an
existing WC.

Don't use made-up terminology. The terms "repository" and "working
copy" have specific meanings. Use those terms to refer to what they
mean. Don't use those terms to mean other things and don't use other
terms to mean those things.

You mean, why svnwcsub.py doesn't pass that option? For starters,
because svnwcsub.py was written before that option existed.

-1. That would be data loss in case of a new svnwcsub deployment where
the target dir already exists and is non-empty. This project is
generally rather averse to the possibility of data loss.
