It sounds like a good change.

We do in GNU ELPA (see https://www.emacswiki.org/emacs/DelightedModes
regarding the one I wrote, delight.el), but that and similar libraries
mostly exist because there wasn't something as trivial as a variable
to set.

Delight also takes care of synchronising the label in `mode-line-menu'
(down-mouse-3 on `mode-line-modes'), as well as allowing custom names
for major modes via the same UI -- but providing an easy way to set
minor mode lighters was the actual reason for writing it.
