Currently, VSCode doesn't show any kind of graphical feedback of where function breakpoints have bound to.

Visual Studio and other IDEs show some graphical feedback to show the function breakpoint has bound to some specific locations / the debugger is in break mode at a particular line because of a function breakpoint.
It would be great for VSCode to support this in the case when debug adapters report the line(s) where the function breakpoint has been bound.

This helps users determine that

• there is a breakpoint that will be hit at some locations
• a breakpoint has been hit when stopped at a function breakpoint.
