This depends pretty much on how GDAL is packaged.
On Unix, the default "make install" target will copy any .py file of
swig/python/scripts/ to the
${install_prefix}/bin directory. And for example Debian/Ubuntu packaging
follows that.
On OSGeo4W, they do that similarly and have a .bat that creates a .bat shortcut
for each
installed .py file

Yes, that the sub files would be available as executable scripts, whereas some
of them would
not be.
One could imagine that the code could go to a Python module (gdal_scripts ?),
and the top-
level gdal2tiles.py could be something like:
from osgeo import gdal_scripts
gdal_scripts.gdal2tiles(...)
I'm not clear what the effort required / benefit would be however.

No opinion on that, having not used any of those. One must keep in mind that
GDAL is not a
pure python project, so not sure how those tools integrate well with the custom
approaches
we might have.
One thing that is missing currently, when comparing to the C++ part, is to get
coverage
information of the Python code.

Clearer variable names are always welcome.
