[Feature Req] In the last 2 years, BCH is the only crypto I have used for payments (like VPN, cross border payments, microdonations etc), in fact everytime I see a crypto payment option, I fire up my wallet, check the fee on BTC, then switch back to BCH f

Here's a proposal, I wouldn't mind paying X% of my transaction to be sent to the dev pool with every transaction. BTC costing $3.5 for a $10 transaction (to use an example). Less than a penny fee is absolutely amazing in comparison, but I can easily send $0.10 to the dev fund for the development for that tx (i.e 1%).

This functionality however is better suited to be built into the wallet (and be configurable).

Considering our blocks are still pretty empty, is there any other technical or economical consideration which prevents this from happening?
