I am using ldd to find the libraries necessary for binaries and had to
adjust my "one-liner" scripts when I moved on from glibc to musl ldd.
I would suggest that it is your scripts which are to be (easily) adjusted,
not the ldd which from my perspective works just fine, for a purpose very
similar to yours.

There is no such standard because the concept of a "dependency
on a component" exists only in a context of a certain packaging
system. Software in general does not belong to a single such context,
so there is no clear notion of components, different parties do have
different views.
