What's with the new obsession of feeling like you have to push every single deer?

Feels like every opponent I come across nowadays at 1300-1500 elo is completely hyper-fixated on pushing all 4 deer under their TC to the complete detriment of their scouting info. Don't get me wrong, I'll push one or two occasionally if it's convenient for me and know that it won't delay my scouting timing, just seems like now 90% of my opponents are way too obsessed with getting every single one under there even when it's completely unnecessary and heavily delays them scouting my base.
