Well, I'd say that can be a per-binding choice (and that depends on utilities.
For example gdalwarp can accept several input datasets). My fundamental question was if my
proposal https://lists.osgeo.org/pipermail/gdal-dev/2015-September/042512.html
was OK at the C API level so as to be able to build upon it.
