I think it's too strong. There will necessarily be exceptions, like pypes.

For the package names, I can give you my experience as ocaml packager. 
Our policy is roughly the same as for python:
- executables keep their upstream names (ex. js_of_ocaml, camlp5, ...)
- libraries take the 'ocaml-' prefix followed by the upstream name as 
much as possible (since these upstream names are known). It leads to 
packages like ocaml-ocamlgraph or ocaml-ocamlnet since ocamlgraph and 
ocamlnet are well-known libs in the community. However when the library 
is just a wrapper for a well-known C library, we drop extra ocaml 
prefixes or suffixes (ex: upstream sqlite3-ocaml becomes ocaml-sqlite3).

So overall, no policy should be too strict: the need for uniformity 
should not make it too hard for users!

&gt;<i> * Also for grouping.  I'd like to add a rule that Development/Python
</I>&gt;<i> is intended for packages
</I>&gt;<i> which provide general development libraries for python, and if the

</I>&gt;<i> other category.
</I>
I don't really agree. The current group policy is the following:
- if it's an application/data -&gt; in the corresponding group.
- if it's a library for development -&gt; in Development/%{the language}.
- if it's a library not meant for anyone to install independently
   -&gt; in System/Libraries.
I'm not sure users would find a benefit to have python for cosmology in 
the Astronomy section and python for Maths in the Maths section and so on.

What I would encourage you to do however is to create a cosmology wiki 
page that describes all the cosmology-features of Mageia.
Best,
