For me net ties and decoupling capacitors are two different and unrelated things.
Both are important, but are different features.
* Net ties are related to netlist management.
* Decoupling capacitors are related to routing constraints management.
This is very different.
I am not sure decoupling capacitors constraints must be fixed at schematic level (at least from the point of view of efficiency), although fixing these constraints at schematic level has an interest: it open the door to an automatic placement of decoupling capacitors.
On the other hand, fixing these constraints at schematic level could creates a lot more work than just made a good layout by a skilled designer, without ensure there is no error.
