Hi,
The following MNWE uses \dodoubleemptywithset. In ConTeXt MKIV it works as
expected, In ConTeXt LMTX an error results.
\starttext
\unexpanded\def\doMyDefs[#1][#2]{\getparameters[MD#1][#2]}
\def\MyDefs{\dodoubleemptywithset\doMyDefs}
\MyDefs[A,B][key=val,k=v]
\MyDefs[C]
\typeTEX{\MDAkey} is \MDAkey. \typeTEX{\MDBkey} is \MDBkey.
\typeTEX{\MDAk} is \MDAk. \typeTEX{\MDBk} is \MDBk.
\stoptext
Possibly, \dodoubleemptywithset is not used anymore in LMTX, in which case
it should be removed. Otherwise this could be a bug. Or maybe I use it
wrongly?
Cheers,
Christoph

There is a fix below but even then your example won't work because
\typeTEX isn't defined.

It's a bug, the wrong argument is passed as comma list.
\permanent\tolerant\protected\def\dodoubleemptywithset#1#*[#2]#*[#3]%
{\doifsomething{#2}%
{\def\syst_helpers_with_set_step##1{#1[##1][#3]}%
- \processcommalist[#1]\syst_helpers_with_set_step}}
+ \processcommalist[#2]\syst_helpers_with_set_step}}

Thank you Wolfgang for the fast response! (And sorry for having provided a
faulty MWE.)
Cheers,
Christoph
