Relax OP_RETURN standardness restrictions

In a recent discussion within the Bitcoin Development Mailing List, contrasting opinions by Greg Maxwell have sparked a conversation regarding the nature of spam and relay policies in Bitcoin transactions. Maxwell has been quoted saying that while spam is an irritant that eventually dissipates if ignored, he also suggests that relay policies should not become more restrictive than the current standards applied to mined transactions. This presents a paradox as both statements imply different approaches towards managing transaction policies.

The majority of Bitcoin transactions, at present, are standard, adhering to established norms without significant deviation. This standardization underscores a stability in transaction practices despite potential external pressures or speculative actions aiming at altering these practices. Interestingly, there's an ongoing dialogue about adjusting relay policies not towards restriction but towards greater flexibility. This shift is anticipatory in nature, aimed at accommodating the potential needs or demands of emerging startups, notably those like a mentioned startup with a recently published whitepaper.

The discourse highlights a proactive stance among developers and contributors to the Bitcoin ecosystem. They are considering adjustments to the relay policy that could preemptively address the evolving landscape of digital currency and its underlying technology. This approach signifies an openness to innovation and adaptation, ensuring that the network remains robust, dynamic, and responsive to the changing needs of its users and stakeholders.
