...the very long story short, your desire is to introduce the RAII idiom
across GDAL codebase. Awesome!
I'm sure 99% of GDAL committers will welcome this idea.
Then, **next** question is how we want to implement it:
using C++11+ features, home-brewed smart pointer class(es), etc.
Upgrading to C++11+ just for the sake of upgrade, makes little sense to me.
Especially if folks are not certain about it, don't use those features daily,
don't feel comfortable...it may cause more harm.
