Well, it has some problems, introducing vertical space in certain
circumstances. Will try to work up a minimal, but two observations:
1. The extra vertical space tends to happen immediately before headings,
which is probably immediately after a \par, suggesting that if we're
already in vertical mode there is something creating a horizontal mode
object here.
2. If I use \dontleavehmode\index{blah} in material that immediately
follows a heading, and just \index{blah} everywhere else, everything
appears to work well with no white-space issues and no headings at the
bottom of the page.
(I can only do 2. easily because I'm generating my code from XML, not
writing directly in ConTeXt, so it's easy to put in a rule that makes
the tag behave differently in different contexts. It's probably
not a solution for anyone else.)

The manual suggests that you can put index calls between a \section
heading and its first paragraph without worry, but for me it breaks the
page-breaking mechanism, allowing the section title to end up at the
bottom of a page like this:
\starttext
\section{Tufte}
\dorecurse{4}{\input tufte \par}
\section{Knuth}
\index{Knuth}
\input knuth \par
\stoptext
Is there any workaround/fix?
can you try (test extensively):
\def\dodoregister[#1]#2#3%
{\dogotopar{\dontleavehmode\doprocesspageregister[#1]{#2}{#3}}}

no, use \dontleavehmode instead
if you see a tex file on the web and wonder why the spacing is messed up
... it's probably because of abundant use of \leavemode
(recent versions of pdftex provide \quitvmode which is equivalent to
\dontleavehmode; taco wrote that patch a while ago)
