currently, dynamic menuentry is enabled as per the following syntax:

grub> menuentry testentry arg1 arg2 arg3 { echo $chosen $1 $2 $3; sleep 1; }

selecting this entry outputs:
testentry testentry arg1 arg2

Please change grub so that $1 refers to arg1, i.e. have $1 start at the first
*argument*, rather than the entry name, since $chosen is already set to the
entry name.

The entry above should then output:
testentry arg1 arg2 arg3
which is more intuitive and shell-like

This feature is currently undocumented so this request should not be a problem
to "affect existing users".

One simple way of implementing it is to implicitly call shift at the start of
the menuentry commands.
