If you want to jump back to the previous message, you can press `p'.
(And M-v is a chord whereas DEL and p are a simple keystroke, so it’s
arguably maximally convenient to duplicate a chord command on a single
key rather than duplicating a single key on another single key.)

The way I look at it, notmuch has two sets of movement keys – n/p and
SPC/DEL.  The former moves by messages, and the latter by screenfuls
(with the added complication that the screenful movement commands also
stop at intervening message boundaries).  I’d prefer to maintain that
symmetry.
