My only issue with removing striped rendering is with memory usage.

I'm running the stable version and was assigned a very dense tileset
earlier in the evening (central Helsinki, complexity over 13 million
according to the number returned by the server.) I saved the SVG
output to test, and the Inkscape process rendering the full zoom 17
image (at 8196x8196) took about 2.5GB of memory, which is a huge
amount for something that runs (for me, at least) in the background.

Maybe the most complex files should be split up. Rendering one quarter
of that file (half the height and half the width) seemed fine.
