🗒️ Summary of this message: The use of OP_2 in Bitcoin Core fails standardness tests and is unnecessarily obscure; OP_TRUE is a better alternative.

Well, frankly I really don't like the idea of using OP_2 just to avoid changing
some unit tests. We're doing something that many people will use for years to
come, that's unnecessarily obscure just because we don't want to spend a bit of
some modifying some tests to pass.

OP_TRUE is the obvious way to do this, and it results with a 1 on the stack,
which plays better with other standardness rules. OP_2 means we *also* may need
to special case having a 2 on the stack in certain implementations of other
standardness rules.
