I'm not sure if I understand you correctly, I don't want to make "flow
by itself pluggable". I want to make the sitemap pluggable, so that I
can plug-in the flow.

I guess this comes down to the question of "what is the cocoon core?".
I talked last year with Stefano about this, and we both agreed that
everything that is not required to run Cocooon, is optional and therefore
a block. And we agreed that flow is optional and therefore a block.
(Stefano, I hope I remember the discussion correctly here).

Anyway, if we look at the current blocks, we have for example an html
block. It is really hard to argument whether this block belongs to
the core or not. The same applies for flow. 

Now, I think answering the question "Does flow belong to the core?" is
very simple as it is introduced with 2.1, so it wasn't in 2.0 and is
therefore an extension or optional. 
I have done many Cocoon projects over the last years and not a single
project requires flow. (And this does *not* imply that flow is useless!)

Making flow optional reduces the Cocoon core.
