I disagree! From a developer and DBA perspective.

This is true, and not a problem.

private).
That's your personal opinion, and I can't deny you that! However, this
is where a (private) synonym comes in most useful and, if I remember my
SQL course from years gone by, exactly what they were designed for.

Not where I have worked in the last 25 years! Big banks, software
houses, Governemnt etc - all have multiple copies of the same
application in diferent schemas in the same database. (Not in production
I agree, but in QA, test and development, it is quite common.)
Remember too, even in these days of VMs, not every company allows their
use!
