Ok, I added this note to README.md, cmake, meson and qmake examples:

# When you don't care about compatibility with libtool's -version-info, 
then you can take the following rules for VERSION in cmake, meson and
qmake:

# * SOVERSION = Major version
# * Major version: increase it if you break ABI compatibility
# * Minor version: increase it if you add ABI compatible features
# * Patch version: increase it for bug fix releases.

(Because yes, you're right that libtool's -version-info is just
pointlessly complicated and messy for people who don't need to care)

Kind regards,
