it allows for lazy practices
Can you explain why it's lazy.
Perhaps lazy in terms of adapting ones thinking to accept that 0,0 in paperspace is the limits of thee printable area.
And that 0,0 could change depending upon what one set margins for in the paper sizes.
That being said one would still need to adopt or adjust title block borders to fit various page size, and margin combinations
only using the edge of the paper as the origin.
However there is then the legacy method of placing plot dots, or other reference devices so that one could simple plot 'extents'
and not bother with setting up ones plotting to any more exacting(predictable) methods.
Then the cad manager and the users need not bother with learning about how to better control their plot processes using named page setups
for that task.
