Well, new tools shouldn’t mean that you have to terminate long-standing business relationships. I’ve found a work-around with the board house so I will keep using them.
I think the better question is whether it is prudent to eliminate the designer’s choice to raster a zone versus tracing a zone polygon. My modest design proves that the latter can generate too big files. If I had the option that was removed from the v5 codebase, perhaps I could have done better.
With the new feature-limiting mechanism that @qu1ck mentioned is in the nightlies, perhaps the polygon mode will generate better output without sacrificing quality.
