  maybe the RTR cisco router feature for sonde-like probing ?

how many ISPs use this and [how] do they
find it helps them operationally?

it has been around for years, during which time
i have heard no actual data wrt its operational utility,
reckon that cisco would be responsive
to ISP suggestions for improvements to it

(if other router vendors have similar functionality
they should probably speak up;
we can put such features in the caida tool taxonomy)

maybe a nanog panel on provider experiences/caveats
on any of such vendor-provided functionality 
is not a terrible idea.
mod all the anxiety involved in sharing such experiences
