As long as the extension --markov=section:<parameters> had not been
discussed, I would have disagreed.
[Options:Markov] would have been used for --markov[=LEVEL[...]],
And [Markov:Section] would have been used for --markov=section.
Now that we think about
--markov[=[SECTION:][MIN_LEVEL-]LEVEL[:START[:END[:
[MIN_LENGHT-]LENGTH]]]]
I would tend to agree with you.
Let's get rid of [Options:Markov], and use [Markov:Default] instead.
And I'll make sure to provide a helpful error message if the section
[Markov:Default] doesn't exist at all.

I would not think that is a good idea, because I wanted to avoid the
situation where a change of a value in one section affects interrupted
markov sessions which refer to another section.

If you want to make use of this, nobody prevents you from using
[Markov:rockyou]
.include [Markov:Defaults]
Statsfile = $JOHN/rockyou.stats
This should work.
