Actually, in lith developers, your reasoning from ordinary continuous
tone developers does not work. If you use Kodalith without agitation,
you're more likely to get distorted lines and fuzzy edges. Similar
will happen to diluted bath. What you need is a developer with higher
sulfite concentration, higher pH, etc. counterbalanced with reduced
agitation.
