I have only a rectangle in my document. When saving as PLAIN svg I get a lot of junk.
(before saving as PLAIN svg I deleted all other unwanted bezier curves)
Seems that INKSCAPE does not register these removals.
When I start a new document with only the same rectangle everything is ok.
A rectangle can be saved in its parametric status (means you can still alter the round corners later on parametrically for instance) or as a path with a stroke+fill, paper size etc; the "junk" just makes clear how the workspace maintained when opened in Inkscape again. Converting the rectangle object to a path and saving as Plain.svg will still contain a hint on the creator software (Inkscape), XML version used and some other defs. I can even strip it down to a three liner which will still display properly if you want to save some extra 300bytes. All this will not save you any disc space BTW as most OS have a minimum file size like 4KB for instance.
BUT where you get unwanted Bézier curves in a rectangle description escapes me.
Would need an example svg file so we can see the problem
