Bug#997879: libsrtp2-dev: pkg-config really required?

[Alexander Traud]

Package: libsrtp2-dev
Version: 2.4.2-2

The developer package of libsrtp2 declares the tool pkg-config as (required) dependency for years now [0]. I was not able to find the reason for this. Please, elaborate why this was included.

There are several voices [1][2] which state that, if pkg-config is not used directly in that package (for example via an own config tool), no reason exists to depend on it at all, even not as Suggests.

Therefore, is it possible to lower or even remove that dependency?
