I’ve seen some rounded tip machetes and I’m curious about why? Thoughts?
100%!!.
Modify the tool for the intended use.
Because that machete lives in a commie country or state...
If you learn machete use and technique from people that use them every day, you'll see that a sharpened tip is normal.
Grass cutting, skinning, skiving, etc, need to be sharp to the tip. Not rounded over.
I've seen and used machete that have been sharpened to a point.
Poking holes, deft slicing, sliver removal, etc.
Modify the tool for the intended use.

All the ones ibever saw old folks use has a blunt, unsharpened tip. These were agricultural implements though.What type of a tip do you think is more appropriate for a machete?
It's a machete, not a katana or claymore.....
Actually, I did. I'm pretty good with one, or was until this old body went kaplooey.If you learn machete use and technique from people that use them every day....
