The engine already sopports import of SVG files, but could really use a way to use it in the engine.
Vectors has a lot of cool uses, and is commonly used around the web, for both animations, and lightweight UI.
UPDATE/EDIT: (edited my original post to reflect the many uses of vector shapes, other than graphics, discussed later in the thread)
I also posted idea here --> construct3.ideas.aha.io/ideas/C3-I-729 explaining how some of the first steps of supporting vector shapes could improve Construct 3.
Reasons for supporting vector shapes in the editor.
First step, Simple shapes and curves (not rendered)
1. Animating objects along paths, curves and shapes. (would be very needed with a timeline feature)
2. Defining areas and collisions. (Could be used as a null object instead of using dummy sprites.
3. Working as null object, and making the use of Dummy sprites a thing of the past.
4. Could be used to deformation purposes similar to how spine and spriter works (deforming shapes along a path, deforming the shape containing a sprite)
Further uses, (rendered shapes)
1. Basic shapes for buttons, UI, icons, etc. (A very lightweight option that would scale well)
2. Import of SVG, for more detailed vector graphics.
3. Support for vector animation and tweeining individual points (much like how Flash used to work)
Some interesting online tools that use vector, to take inspiration from.
Proto.io
Very powerful prototyping tool i often use to make UI prototyping for apps and web.
proto.io/en/demos (take a the whack a monster demo)
Animatron
A pretty nice timeline animation editor, which is pretty close to how I invisioned the upcoming timeline feature to be implemented. Open link and check some of the examples. Really cool and easy to play around with.

Gravit.io
Very cool and competent online design tool.
designer.io
Vectr
Nice online editor that supports
vectr.com
svgator
No need to explain, just look at these beauitiful animations, that would fit well in any game.
