Apologies for all the MathML queries. Here are two more, embedded in one
test file which will run on live.contextgarden.net:
--
\usemodule[mathml]
\setupwhitespace[medium]
\starttext
\TeX{} maths aligns $x$ well.\par
MathML aligns
\startXMLdata<imath><math><mi>x</mi></math></imath>\stopXMLdata squashed
to the right.\par
Also:\par
\TeX{} display maths makes text go smaller for fractions inside fractions:
$${{\rm Q}\over{\rm P}}\over{\rm R}$$
I'd like the same to happen for MathML:
\startXMLdata <formula><math><mfrac><mrow>
<mfrac><mrow><mtext>Q</mtext></mrow><mrow><mtext>P</mtext></mrow></mfrac></mrow>
<mrow><mtext>R</mtext></mrow></mfrac></math></formula>\stopXMLdata
\stoptext
--
In summary:
#1 Inline MathML has a wide space before, and no space after.
#2 Display MathML doesn't reduce font size for <mtext> content such as
fractions within fractions.
I have done a fair bit of source- and archive-surfing on both these but
no luck. Many thanks for any help.

mtext is a hbox; try
$$\frac{\frac{\hbox{\rm Q}}{\hbox{\rm P}}}{\hbox{\rm R}}$$
in mml we have:
startXMLdata
<formula>
<dmath>
<mfrac>
<mrow>
<mfrac>
<mrow>
<mi mathvariant='normal'>R</mi>
</mrow>
<mrow>
<mi mathvariant='normal'>P</mi>
</mrow>
</mfrac>
</mrow>
<mrow>
<mi mathvariant='normal'>R</mi>
</mrow>
</mfrac>
</dmath>
</formula>
\stopXMLdata

the space before is a bug: in xtag-ini, locate:
.unexpanded.def<B.doXMLelementE*
and add the * (comment token) which prevents the spurious space. (interesting
that this went unnoticed so long)
the space after ... well, it took me a while to notice that this is expected
behaviour (space after \stopXMLdata is naturally gobbled):
MathML aligns \startXMLdata<imath><mi>x</mi></imath>\stopXMLdata\space
squashed to the right.\par
\startbuffer
MathML aligns <imath><ci>x</ci></imath> squashed to the right.
\stopbuffer
\processXMLbuffer

Thanks a million Hans. I guess my only issue now is displaying spaces
within text inside what I used to have as <mtext>, but that can be done
explicitly with <mspace> elements for the time being.
Thanks for taking the time to understand and solve.

btw, can you add your test/example code to the wiki (mathml corner; we can also
collect wishes there)?
