This is the *why* of the SIP. It should clearly explain *why* the current state of the protocol is inadequate.  It is critical that you explain *why* the change is needed, if the SIP proposes changing how something is calculated, you must address *why* the current calculation is inaccurate or wrong. This is not the place to describe how the SIP will address the issue!-->\n<p>The intent of this proposal is to provide governance with maximum flexibility in controlling fees where they may be levied by the core protocol.</p>\n<h2 id=\"rationale\" style=\"position:relative;\"><a href=\"#rationale\" aria-label=\"rationale permalink\" class=\"anchor before\"><svg aria-hidden=\"true\" focusable=\"false\" height=\"16\" version=\"1.1\" viewBox=\"0 0 16 16\" width=\"16\"><path fill-rule=\"evenodd\" d=\"M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z\"></path></svg></a>Rationale</h2>\n<!--This is where you explain the reasoning behind how you propose to solve the problem. Why did you propose to implement the change in this way, what were the considerations and trade-offs. The rationale fleshes out what motivated the design and why particular design decisions were made. It should describe alternate designs that were considered and related work. The rationale may also provide evidence of consensus within the community, and should discuss important objections or concerns raised during discussion.-->\n<p>By relying on a standardized interface for a smart contract to process fees, governance will be able to update the distribution of fees in addition to the amount of fees collected. The fee recipient could be an EOA, a <a href=\"/sips/sip-305\">rewards distributor</a>, or any other smart contract.</p>\n<h2 id=\"technical-specification\" style=\"position:relative;\"><a href=\"#technical-specification\" aria-label=\"technical specification permalink\" class=\"anchor before\"><svg aria-hidden=\"true\" focusable=\"false\" height=\"16\" version=\"1.1\" viewBox=\"0 0 16 16\" width=\"16\"><path fill-rule=\"evenodd\" d=\"M4 9h1v1H4c-1.5 0-3-1.69-3-3.5S2.55 3 4 3h4c1.45 0 3 1.69 3 3.5 0 1.41-.91 2.72-2 3.25V8.59c.58-.45 1-1.27 1-2.09C10 5.22 8.98 4 8 4H4c-.98 0-2 1.22-2 2.5S3 9 4 9zm9-3h-1v1h1c1 0 2 1.22 2 2.5S13.98 12 13 12H9c-.98 0-2-1.22-2-2.5 0-.83.42-1.64 1-2.09V6.25c-1.09.53-2 1.84-2 3.25C6 11.31 7.55 13 9 13h4c1.45 0 3-1.69 3-3.5S14.5 6 13 6z\"></path></svg></a>Technical Specification</h2>\n<!--The technical specification should outline the public API of the changes proposed.
