Move \showlayout *after* \starttext or add \setupbodyfont[modern] *before* \showlayout.

It's ok (as also the Wolfgang replay)
but this works
\showframe
\starttext
\input knuth
\stoptext

so I expected the same for this
\showlayout
\starttext
\input knuth
\stoptext

which looks more consistent.

Of course this is ok
\starttext
\showframe
\input knuth
\stoptext


but showing meta informations between \starttext \stoptext it's a bit strange.

When you’re use \startproduct or \startcomponent you’re always after \starttext.

The reason why nothing was shown in your example is that font loading is postponed till \starttext in mkiv.

it's not meta-info ... it's typeset content

paperwidth, paperheight, bodyfontsize, the frames etc are meta-info of
the document

yes, but they are *typeset* so we need to start the text first
