Hi Jano,

Seems to me that there are a few options and you might need more than 
one of them, depending on the font/typefaces you are using (which 
obviously influences things):

1. One factor will be whether you are using \definefontfeature 
[default][default]  [expansion=quality,protrusion=quality], which you 
obviously then need to call in with \setupalign. 
https://wiki.contextgarden.net/Command/setupalign

2. Another factor will be \setupspacing 
https://wiki.contextgarden.net/Command/setupspacing

3. A third factor might be the need to tweak things a bit once you take 
a look at what is produced, and where you might need to use a couple of 
other options, be it \, \nospace, \thinspace....

For example, I have found that for a particular project I am working on 
at the moment, my best setup does not include protrusion, but I use

\setupalign
[hz,nothyphenated,verytolerant,stretched], and

\setuplanguage[en][spacing=packed].

This latter especially because I want to avoid some rather ugly spaces 
after a period. Then once I see how things look, I apply 
{\kerncharacters[-0.025] my text} in particular instances where things 
need to be tidied up. I have found that -0.025 works well in my situation.

Not at all sure if all the above is what the purists would do, but from 
a practical point of view it works for me. Hope it helps.

Julian
