Backquotes, aliases get 'em, BTMs don't?

Is that right ... backquotes are passed to aliases but not to BTMs? I was a little surprised. Is that WAD?
Code:
v:\> alias eeval
echo %@eval[%1]
 
v:\> eeval `1+2`
TCC: No expression "`1+2`"
 
v:\> type eeval.btm
echo %@eval[%1]
 
v:\> eeval.btm `1+2`

WAD. Back quotes are removed after alias & variable expansion is performed, and just before the command is passed to the parser routine that sends it to the appropriate place for execution (external app, batch file, or internal command).

If back quotes were removed before alias expansion, they'd be completely useless.
