I think the bag is very handy to have.
There were many times I also thought about removing it, mostly because I like the look of it from some angles but less from other angles.
After procrastinating, I decided that it’s more handy to have it should i need to carry small items (sunglasses, paperwork, rolls of cash, etc)
I think it doesn’t detract from the look of your bike and it’s a useful little bag.
Also, I understand it’s impossible to find black ones anymore.
