​There are in fact precedents for doing something of the sort. But not ones
that I think we should follow.

DNSSEC would have been implemented as part of the VeriSign ATLAS roll out.
The reason it was not was it simply could not be deployed using the tech
available with the spec as it was at the time without a major increase in
cost and complexity.

A blanket requirement for open source implementations may well have the
same effect.

Operating systems at Internet scale is vastly more complex than running
systems at network scale. It is not just the genius of the original
Internet designers that has allowed the Internet to scale from 100 nodes to
10 billion. There is a vast amount of unseen engineering work that is
equally heroic and some of that infrastructure comes with some very
specific constraints.

Some of the most useful work in IETF is making closed systems more open.
Often those projects require some extra slots to carry information that is
needed for some legacy system. I see no value to saying folk can't have a
smooth transition path from proprietary to open.
