Yes, I fully agree.
Special (or pseudo) components have many advantages: for instance
- no specific code to load/save/edit/draw/plot components in schematic
- free shape instead of fixed shape.
- they can be connected to a net (or 2 nets) by pins.
- a footprint can be defined (therefore the object which will be put on a board)

So, as long as one can use a "component" for a net tie schematic symbol, this is certainly a good idea.

Of course ERC and DRC modifications are still needed.
Especially, DRC modifications are not easy.
