Subject RE: [ALL] Volunteers for a Math PPMC?

I see, by being allergic to cross-posting, that I have created the mess I hoped to avoid. 
There are matters here for keeping the Commons Math folk involved so I won't say much here.
 This needs to be addressed at dev-commons.

A couple of comments in-line,

I asked because there are those who propose retiring portions of Commons Math that no one
is maintaining (with some confusion between "stable" and "unmaintainable") The current collection
of packages seems to include some that are more than "small easily-integrated components [without]
complex dependencies and configurations."  That appraisal is definitely superficial on my
part, though.  This is not an expert assessment.

About attic and forking.  I meant whether the code base that is at Commons Math would be frozen
and in the attic although available for use, just not maintained there.  Folks could be advised
that there is continued development downstream from there in an Apache (podling) project and,
if it graduates, a different TLP.  

Do not assume that graduation of a Podling is a slam dunk.  

"Fork" is not a toxic notion at the ASF, although I understand that the current existence
of non-ASF Commons Math fork is bothersome to those who have put their hearts into Commons
Math and have not defected.

There are a number of technicalities in moving that need to be identified and prepared for.
 Those need to be comprehended (and apply to direct-to-TLP as much as direct-to-Podling).
 It may be just a matter of having greater clarity and appraisal by the Commons Math community.

I am certain that there are Incubator folk who can advise and assist in all of this.  Meanwhile,
the Commons Math and Commons community needs to be on top of the considerations enough to
choose an informed path.
