There is certainly a trade-off here between ease of contributing and having outdated examples. 1.0 may be around for at least a few years, but standard libraries can potentially change even during that timeframe, and 3rd party libraries are moving at a very quick pace, with some releasing multiple new major versions in a year.
At the same time, the presence of outdated code snippets on the net is already a concern for some (but of course we cannot do anything about that and all languages which are developed actively have this problem).
I think the ideal to strive for is having an API and documentation (with examples etc) that makes things so intuitive and well-explained that “pro tips” are not needed at all.
