I play a dedicated herbalist, and I'm actually against reducing the weight of the herbalism bags. This change really only benefits clerics (and maybe paladins), as other heavy armour users typically have a higher strength score due to not having to worry about boosting a casting stat.
Alternatively, they have super high dex scores and don't use heavy armour/shields in order to maximize parry/dex AC bonuses
Inventory management can seem tedious to some players. I personally very much enjoy it. I've played low strength characters and high strength characters, and with both, I've always enjoyed maximizing my utility and minimizing carry weight.
The major problem I see is that players are always stuffed to the brim in terms of carry weight. Most casters can't even run unless they pop a bulls strength. I'm ok with that. You do you. But its not something I do myself on characters I play. My rule of thumb is to keep my carry weight at 2 strength points lower than my actual maximum. Strength drain is real, whether from ghosts that attack you when you go through a transition, to crippling strike rogues ganking you.
The other reason for this is for the sake of my party members. If one of them gets corpsed, then I can usually save them. Why? Because since my carry weight is kept far lower than my max, I can toss them into a magic bag and run my booty on outta there.
In short, if you choose to keep your strength low to maximize effectiveness elsewhere, then you should have to deal with the consequences of that. Just like we don't have bags of holding, we shouldn't continuously lower the weight of items to satisfy the stat requirements of already very potent characters. Reducing the bags from 0.5 to 0.1 is an 80% reduction on an empty bag, and a 16% reduction on most full bags (assuming the full bag weighs 2.3 to 2.5 lbs).
