before coming to Brejlov I am just about to clean all my open threads regarding 
transition MkII->MkIV.
One thing is still unanswered - related to grid mode:

In MkII the example below rendered the same with or without grid mode.
Now in MkIV the lineskiplimit is overruled by grid mode.

forget about comparing to mkii .. a completely different mechanism and behaviour will not be mkii compatible (different kind of control)

But as I still have to use grid, and yet have to make sure that character 
clashes don't disturb the consistent interlinespace, I have a problem.

in grid mode interlinespace is ignores

Looking through spac-ver.mkiv gave me the impression that lineskip related code 
is quite ... precarious.
But maybe an unofficial hack is doable?

no hack needed

\enabletrackers[nodes.vsnapping]

\starttext % see spac-ver.mkiv: \definegridsnapping

    \switchtobodyfont[42pt] \setupinterlinespace[line=30pt]

    Big text\par written in\par three row

    \setuplayout[grid=strict] \setupinterlinespace[line=30pt]

    Big text\par written in\par three row

\stoptext

with 'yes' the line gets snapped to fit an extra line when too high (ht/dp ratio) and your first line is larger than the second and third
(try {yes,line} so see a variant).
