Ok, I came up with a solution that seems to work:
\def\definesection[#1]%
{\doifundefined{\??se#1}
{\doifelsenothing\firstsection
{\def\firstsection{#1}%
\setevalue{\??se#1\c!before}{\v!text}%
\setevalue{\??se\v!text\c!after}{#1}}
{\setevalue{\??se\commalistelement\c!after}{#1}%
\setevalue{\??se#1\c!before}{\lastsection}%
\setevalue{\??se\lastsection\c!after}{#1}}%
\advance\nofsections \plusone
\setevalue{\??se#1\c!level}{\the\nofsections}%
\letvalue{\??se#1\c!after}\empty
\setvalue{\e!next#1}{\@@nextsectionnumber{#1}}%
\setvalue{#1\c!number}{\@@longsectionnumber{#1}}%
\setvalue{#1\s!format}{\@@longformatnumber{#1}}%
\setevalue{\??by#1}{#1}%
\setevalue{\??by\v!by#1}{#1}%
\makecounter{\??se#1}%
\makecounter{\??se lastvalueof#1}% GB
\edef\lastsection{#1}%
\setvalue{\??sk#1}{#1}%
\letvalue{\??se#1\c!marking}\empty
\setupsection[#1][\c!previousnumber=\v!yes]}}%
% New command preserves the value of the next sectionlevel
% when resetnumber=no
\def\checkpreservevalueafter#1%
{\ifnum\getvalue{\??se#1\c!level}<\the\nofsections
\edef\preservedsection{\getvalue{\??se#1\c!after}}%
\ifconditional\@@resetsubheadnumbers
\setcounter{\??se lastvalueof\preservedsection}%
{0}%
\else
\setcounter{\??se lastvalueof\preservedsection}%
{\countervalue{\??se\preservedsection}}%
\fi
\fi}
\def\@@setsectionnumber#1#2%
{\letgvalueempty{\??se#1\s!start}% signal i.p.v. boolean
\setcounter{\??se#1}{#2}%
\checkpreservevalueafter{#1}
\resetsectioncounters{#1}
\checkpagecounter}
\def\@@nextsectionnumber#1%
{\letgvalueempty{\??se#1\s!start}% signal i.p.v. boolean
\ifnum\countervalue{\??se lastvalueof#1}>\zerocount
\setcounter{\??se#1}{\countervalue{\??se lastvalueof#1}}
\setcounter{\??se lastvalueof#1}{0}
\fi
\pluscounter{\??se#1}%
\checkpreservevalueafter{#1}
\resetsectioncounters{#1}
\checkpagecounter}
This has been tested in a fairly complex document (some
levels with resetnumber=no, some with the usual resetnumber;
sectionblocks etc). It works, and fixes the placecontent not
working. Will this go into mainline?
