Well, I am writing portable makefiles that are expected to work even on UNIX 
versions from 1984, so I did not have $() on my radar.

Also note that POSIX does not require /bin/sh to be a POSIX shell. Solaris 10 
e.g. is POSIX certified, but comes with the historic Bourne Shell as /bin/sh 
that only supports backticks and I added $() support to the Boure Shell in 
March 2016, which is not really long ago.
