If post hf25 this remains an issue we could introduce a change in hf26 to be able to reduce the proposal but also bring it back to it's "max" depending on HBD price.
But it goes against the initial idea of the feature where you want to create a proposal at a price and if the community feels like you're asking too much you can reduce it but not increase it again, so it could create a risk where you set 200 per day, then community makes you go to 100, you get voted and then you increase it back to 200.
