Just realized Str and a half to 2h is gone.

Not sure that is is bad a lot of 2h weapons have properties that add damage it just feels weird for someone who started with 3.0 it has always been there.

Yep I think this one falls into making the game easier to teach. Having to half odd numbers and round down and then add that to the damage is a lot to do for a point or two of damage.

I think it's more for balance reasons. In PF1 the 1 1/2 damage (together with the same for power attack) was what made 2 handed weapons so effective that sword and board was just left in the dust comparatively speaking.

Its partly balance, and partly doesn't matter enough to do.

Keep in mind there is a hard cap of stats in this edition-
20 at 10th level
22 somewhere in the teens with an Apex item, and 24 at 20th (with said Apex item).

So it would be +2 damage from levels 1-9, then +3 depending on how you're rounding and maybe +4 (if rounding up) at 20th.

In 1e it was quite possible get up around 30-odd strength by level 5 (4th level alchemist- strength mutagen and bull strength and a level of barbarian)

I mean, the damage die for the deadliest 1h weapon is 1d8, whereas the damage die for the deadliest 2h weapon is d12. So from from levels 1-3 (before you have a striking weapon) the 2h weapon will outdamage the 1h weapon by 2, from levels 4-11 (before you have greater striking weapon, the 2h weapon will outdamage the 1h weapon by 4, and from 12-19 the 2h weapon wins by 6, and 8 at 20th.

Also, since 2h weapons tend to have more or better traits. I think that's more than enough incentive to use a 2h weapon.
