Sure, and that's why I'm trying it out now, to provide feedback.  But 
because I couldn't tell from assoc and ftype commands that it had done 
anything, I was a bit surprised by the behaviors I did encounter when I 
encountered them.  So now I've learned about the limits of ftype and 
assoc, sadly.  And they only work for setting things in HLM if you "Run 
as administrator", by the way.

Wonder if there is a third party command line tool which augments them 
for reading/setting HCU Classes?  Will search.  I know there is a 
command line registry tool somewhere, but specifying the paths correctly 
would be onerous.

Would be nice if the default of Py 2.x or 3.x were an install question, 
perhaps.  I know that only affects scripts without #! lines, but it 
would be nice to limit the required creation of those to the smaller 
class of preexisting scripts on a particular installation.

Could be, with .msi and/or .cab installers.  I have no knowledge of 
them, except that when I first needed to use an installer to package 
things, I read a bit about them, and determined that they are too 
complex for my brain.  I found NSIS, still complex, but it is much 
friendlier to my brain, but it seems to handle this case correctly, 
giving the installer creator the option of asking for or demanding 
elevation, and exposing the answer to the rest of the logic of the 
installer, so it can do different things for those cases if it desires.
