It depends.

Linux/Unix have more or less typical layout of libs and binary files. 
Many Linux distros have package managers.

Windows has none of the above. So you can't go closer to Linux there. 
You have to choose different way.

If you want to have simple install for python-based bzr version then it 
makes sense to look at setuptools and easy_install (though me does not 
like it very much). Then user only need to install Python and maybe 
setuptools and then `easy_install bzr` will do the magic.

Standalone bzr.exe is standalone program. You can put every plugin 
inside it and then all required dependencies will be bundled as well. As 
result you'll have ~30-60MB installer that should work for everyone.
(AFAIK TortoiseHg distribution with GTK libs inside is about 30MB).

The only one problem today is all installed plugins are enabled 
implicitly. In hg user have to enable plugins manually. So hg developers 
can ship standalone hg.exe with all official plugins inside.

Bazaar can ship all plugins as well, but it will require some changes to 
installer to allow the user to select which plugins to install. Not the 
worst way IMO.

Is bzr.exe really needed? Some facts:

1) today nobody provides windows installer for bzr-svn plugin separately 
of official bzr.exe build. And building bzr-svn on Windows is hard hard 
work. Do you want to drop this beautiful plugin @ windows?

2) the same applied to TortoiseBzr which should be compiled today.

3) In my observation standalone bzr.exe works a bit faster on Windows; 
mostly because all pure python modules packaged into one big 
library.zip, so Windows need to read only one file from disk instead of 
zillion files (including py/pyc/pyo difference). This is very important 
to get better performance: less files to read means faster windows 
application.

4) You're starting this discussion again and again, but if you look at 
download numbers (they are available now on LP) you'll see what users 
prefer. Of course one can say this is because it's default installer. 
Yes, of course. But I think it suits needs most of users. All other who 
need something non-default have to deal with python-based version.

Of course things will be much simpler if there will be enough windows 
maintainers who will provide installers for all popular plugins. But 
there is not, and therefore you have what you have.
