[2] By easily managed I don't mean sed-able, or even tooling-fixable. For me it pivots on being able to maintain one code-base that will compile with multiple compiler versions. An example where this fails: @nogc, being an attribute, isn't aliasable, meaning you can't version it out neatly.
There is nothing stopping you from not supporting @nogc until your oldest supported dmd version has it. I agree with your requirement, but this is not a good example of it. A better example would be requiring nothrow annotations on inline asm blocks, because the old code won't compile with newer dmds and the new code won't compile with older ones.
