It would be a straight multiplier to the alpha of the pixels, just like how (i think) it is now except you could also make something 'more' opaque than normal. This would be useful for say blurred objects that became too transparent.

I am pretty sure this would invalidate the css according to w3c but isn't that why there is inkscape-svg and plain-svg?

No. Not at all. Inkscape SVG is valid SVG. It does not break the standard; it just adds to it in areas which are not covered by the standard, such as metadata and editing behavior. What you propose would break SVG compatibility and therefore is not acceptable.

When saving to plain-svg a file with something like 250% opacity, it could be layered like 2 100% objects and a 50% object which I believe would then be ok.

That is possible in principle _only if_ it's used in all SVG, plain or not, that Inkscape creates. But I'm not so sure that this would be such a useful feature, while implementing it would be quite a hassle. You can always do the same very quickly just by cloning the blurred object.
