Uhm. I can't think of any example like that, really. The point is that in ConTeXt as it is now a display (formula, itemization, quotation, etc) is always forces a paragraph before and after, which is not consistent with what the writer might want; think for example of something like:

This is where we differ. After all, the empty line is the *standard* TeX (and ConTeXt) way to denote new paragraph. While should it be different for displayed items? It's inconsistent.
An introduction to the following:
- itemization
- one more item
and a conclusion, all in the same paragraph

But I have to specify it manually. If I later decide to rewrite the stuff so that it's really in separate paragraphs I have to change the displayed environment, while what should suffice is letting ConTeXt understand that a new paragraph is started --the *standard* way (empty line).
Doesn't work. Try setting \setupindenting[medium] in your example; you'll notice that each line starts a new paragraph, and this is not what is wanted.

I don't think there should be any need to look back or ahead. Just don't force a new paragraph before and after each displayed item. Let the user choose, the standard way(s).
I propose a global switch like
\setupstartstops[break=always] % current ConTeXt behaviour \setupstartstops[break=par] % only start new paragraphs % when there are empty lines
HH> hm, not sure it it hooks/should hook into start/stop
Where should it hook? All displayed items are start/stop pairs. If you want to overrule this for a specific start/stop pair, you can always to it with the local switch:
and local switches like:
\setupquotations[newpar=always] % current behaviour
where newpar can be always, (current behaviour, regardless of global setting), default (follow general \startstop behaviour set up by \setupstartstops) or par (start according to empty lines regardless of global setting). Does it sound sensible?

"Display" is just a generic term I'm using for all the stuff which is part of a paragraph but gets "highlited" by typesetting it in a different format, sort of like a subparagraph. This category includes itemizations (all itemgroups, actually), formulas (not inline, of course), quotations, etc.
