Let's do.  In the context of why Forth might find quotations useful
i.e. one line code fragments that don't deserve a separate definition,
name, testing or own locals - can you give a simple example of a
quotation where accessing the parent's locals would have dire
consequences?

As for implementing such quotations, it should be easy - load the
quotations code before the locals code.  There will be things you
can't do inside such quotations e.g. EXIT but then ANS locals
came with usage restrictions, so what.  I can accept quotations
with restrictions - but quotations that couldn't access the parent's
locals I would regard as useless.
