https://autotools.io/libtool/version.html suggests that instead of 
combining -release and -version-info, one should encode the version in 
the library's name.

The code to determine name of the dev symlink name looks like this:

$link_file =~ s/-[\d\.]+\.so$/.so/o;
$link_file =~ s/\.so.+$/.so/o;

So it doesn't seem to support the combination of -release and 
-version-info.

Probably (sort of) yes...
