I agree!
But after using a Tools Keymap for so long now and trying to use them interchangeably or even mixing the shortcuts up I have to add this: Using one or the other requires a very different muscle memory.
It’s very hard to switch to Tools if you are used to the Operators and vice versa.
So when it comes to shortcuts most people will likely completely choose one or the other.
There are examples of Tools that are great to use together with modal operator shortcuts, especially together with right click select.
Like the Polybuild tool in right click select but those examples are rare.
In the case of that Tool you can get a lot of functionality for your left click + in combination with modifier keys while still being able to select with right click and extruding, bevelling, etc via shortcuts.
I also listed more of my experience and thoughts over here if anyone is interested:
