I had a problem caused by the broken definition lists. If you have a maths equation aligned as a block using a dl ie
then you can't add a non indented paragraph after it. https://en.wikipedia.org/wiki/Wikipedia:VisualEditor/Feedback/Archive_2014_2#Trying_to_add_a_line_after_an_equation
This has some impact on Bug 61051 about how MathJax equations are aligned.
Note that VE supports "bulletizing" lines inside a definition list and they end up properly indented.
For example, using VE to highlight 1, 2, and 3 on a page with the following wikitext
: 1 : 2 : 3
and clicking "Bullet list" results in
:* 1 :* 2 :* 3
Seems like this is a good start on some sort of broader support for arbitrary indention.
