It would also be great if Blender had a way of having drawings natively in a blend file - without the need to use Inkscape. These drawings would harness the LineArt modifier. They could also contain views of different scales and shading/rendering. Maybe this could be done with the Story Board addon?
Grease Pencil 3.0, which is a complete rewrite of the Grease Pencil code may be what we are looking for. As grease Pencil as already vector-based, it works with the line-modifier, has vector fill, and hopefully with the new version, it can perform well with thousands of strokes/curves. I believe it can also be exported as SVG natively.
Here the link: https://code.blender.org/2023/05/the-next-big-step-grease-pencil-3-0/
It didn't land in Blender 4.0, but it is scheduled to come hopefully in 4.1 You can already test it out in 4.1 alpha version at https://builder.blender.org, by going into Preferences, Interface, enabling developer extras, and then in the Experimental tab, enabling Grease Pencil 3.0

I am in general of embracing as many of the existing Blender features into AEC workflows as possible. This may be a good one!

Sometimes, trying to put everything in one program is not realistic, when the development team is too small. Interoperability between open source tools is the best strategy for a feasible workflow in these conditions.
Yes, at the same time, I imagine we would still need to post process drawings in one way or another. If you think about it, it works like that everywhere. We have the design phase, and the documentation phase.
