Who is doing that though? Knots advocates? Bitcoin is 15 years old and the quantity of those transactions as a percentage of the overall compared to other blockchains is vanishingly small. Changing default policies by sneaking in an upgrade via the inertia and the apathy of node operators, and the trust they have for the long standing credibility of Core developers, is what will invite content rich transactions to a degree that makes Bitcoin a useful tool for non-monetary data transmission and storage.

Basic information theory prevents a rigorous absolute solution, so we are left with the sufficient policy and cultural layer.
