Why don't you test if the attribute is set before applying it to the TR?
You see the problem on the last row, but the fact is that you force the
bottomframe clear for every row (which is dirty IMHO).
It's not that easy, since the bottomframe - once set - is persistent ...  
so
every row underneath my header (e.g.) will have 'bottomframe=on' set.
No, the options are local to the current level where it is set. If  
bottomframe is on for one row, it won't set bottomframe to the next rows.  
In the following example, only two rows (the header and another one in the  
body) have local bottomframe on, and the last row bottomframe is done with  
table setup:
\starttext
\setupTABLE[frame=off]
\setupTABLE[row][last][rulethickness=0.90pt,bottomframe=on]
\bTABLE
\bTABLEhead
\bTR[bottomframe=on]\bTH a \eTH\bTH b \eTH\eTR
\eTABLEhead
\bTABLEbody
\bTR\bTD bla \eTD\bTD bla \eTD\eTR
\bTR\bTD bla \eTD\bTD bla \eTD\eTR
\bTR\bTD bla \eTD\bTD bla \eTD\eTR
\bTR[bottomframe=on]\bTD bla \eTD\bTD bla \eTD\eTR
\bTR\bTD bla \eTD\bTD bla \eTD\eTR
\bTR\bTD bla \eTD\bTD bla \eTD\eTR
\eTABLEbody
\eTABLE
\stoptext
You can also put bottomframe only for a cell with  
bTD[bottomframe=on]...\eTD.
the following patch will permit negative numbers (remove empty lines due 
to mail mess up)
