The following example works with older versions of ConTeXt, such as the

With the 20150325 ConTeXt, there are .tuc file entries like:
["second"]="\\hbox {\\simplealignedbox {\\IDWidth
}{left}{2\\quad }{\\doboundtext {Yet another list testing text xxx
xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
xxx}{\\STWidth }{…}}}",
but with more recent versions, the corresponding entry is:
["second"]="\\hbox {\\simplealignedbox {12.6pt}{left}{2\\quad
}{\\hbox {\\setbox \\scratchbox \\hbox {Yet another list testing
text xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
xxx
xxx xxx}\\scratchdimen \\dimexpr \\textwidth -12.6pt+1cm\\relax
\\box \\scratchbox }}}",
\unexpanded\def\STWidth{\dimexpr\textwidth-\IDWidth+1cm}
Yes, expansion needs to be delayed to get the current dimension when
the list is placed. My error—thank you for the correction. But the
regression is not resolved. The .tuc file now contains:
["second"]="\\hbox {\\simplealignedbox {12.6pt}{left}{2\\quad
}{\\hbox {\\setbox \\scratchbox \\hbox {Yet another list testing
text xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx
xxx xxx xxx}\\scratchdimen \\STWidth \\relax \\box \\scratchbox }}}",
Still no mention of dobounded text is carried into the list.
Is \limitatetext a option for you because unlike \doboundtext the
command is unexpandable?
\starttext
\doboundtext {Thus, I came to the conclusion that the designer of a new
system ...}{.5\textwidth}{...}
\limitatetext{Thus, I came to the conclusion that the designer of a new
system ...}{.5\textwidth}{...}
\stoptext
