how should .pc files be configured for "static only" builds?

[Roger Pack]

It's come to my attention the following conundrum:

https://www.flameeyes.eu/autotools-mythbuster/pkgconfig/dependencies.html

in my own words, it seems impossible to know if, when calling
pkg-config, the library was compiled statically or dynamically" (so
you don't know whether to call pkg-config --static or not).

Has there been any improvement/progress on this as of late?
Thanks!
