Selecting/Creating waypoints has been a digital mapping-feature of every service/tool I have used since digital mapping/navigation became a thing. From garmin hand-held off-road GPS topo navigation systems to units used for fishing to hiking/biking.

It has been a cornerstone of digital navigation since the things were invented. To claim that it's an edge-case ignores history and instead highlights how _you_ use the tools.

IMHO it was more obvious that Google wants to you 'actively search' for $waypoint item while enroute instead of pre-planning. "hey google, show me restaurants near me"

That gives them a better way to monopolize on advertising and forced $ from companies in order to stay relevant and appear in those type of searches.
