Because the C++ ABI was not stable in the past, see:

Maybe it is now, but it was not in the past.

GDAL 2.3.0 will be the first release for which I'll try not to bump the
virtual ABI dependency (keeping it at gdal-abi-2-3-0) to see if C++ ABI
is now actually stable. If that fails, the virtual ABI dependency will
be changed for every patch release again.

Kind Regards,
