The issues matter because of usability.

Is there any other solution than double-entry in this case, to have
both a closed internal representation which can be rasterized at
arbitrary resolutions, plotted as gerber/ps *and* a closed system
for user input<->output ?

As a bonus, double-entry would allow internal consistency checks to
some degree.

Yes, it's a lot of work.
