I think preventing frame resizing is the right move, at least in the context that I had in mind (screen sharing): if you scale the frame and the font at once, then nothing changes on the recipient's screen (since the videoconferencing software scales the frame to a constant size).

(Besides, that's what menu-set-font does; and it's easy to resize the frame after scaling the font, no?)
