Will it be possible to use single color SVG vector imported?

There is native SVG / spline support on the UF roadmap: https://www.filterforge.com/images/ult...lines.avif -- but don't expect it in the first release.

As for the single-color / mutli-color / SVG fills, we're still undecided. Ideally you should be able to import any SVG, with colors / fills and multiple spline shapes, then disassemble / dismantle it via nodes into separate Bezier splines.

The problem is that many Bezier operations (e.g. booleans, outline-to-spline, etc) don't need color, or, in case of Boolean, mess it up. So the question is, will our Bezier splines be colored / filled, or they will be just splines without a fill, and the fill will be applied later via some special SVG-producing nodes.
