Nothing special, I always expect interline space to be fixed, I don't know if TeX always make interline spacing variable, but this wasn't an issue with English text. However, with Arabic, Tashkil marks seems to always cause a noticeable extra whitespace above the line. See the uneven distribution of vertical whitespace in this example (it can be even worse than this in reality):
for arabic you really need to set the interline space (idris might have more input on this) - it has more height than depth - vowels add to the height of the line - tex adds some interline space when lines touch
\usemodule[simplefonts] \setmainfont[Arabic Typesetting][features=arabic]
\starttext \pardir TRT\textdir TRT \dorecurse{10}{\dorecurse{20}{نص عربي } نَصُّ مُشكَّل \dorecurse{20}{نص عربي}} \stoptext
