Probably, this is well feasible, but IMO, it would be really worthwhile
to - optionally - enable the usage of an external tool to do dependency
scanning, for new languages as well as for the premier ones like C/C++
in case one wants to overcome the built-in scanner's shortcomings while
accepting certain performance penalties. There has already been some
considerations and requests in this regard, e.g.:
