In Concern about recent closures of community wiki questions the community spoke very clearly about not wanting as many of the highly upvoted community wiki questions closed, even though they would be closed as too broad if asked today.
In response to that, and a suggestion by @blah238 in comments, some were re-opened and converted to the yet to be fully documented wiki answer locks as a bit of an experiment, and that seems to have been accepted/supported (or at least not complained about) by the community.
If anyone is concerned about that could you describe that concern in an answer here, please?
Note: This question is asking only about the wiki answer lock placed on the particular question of How to Start Web Mapping? but ...
If you ever think there is any question that has been closed (not locked) inappropriately, and you have the privilege level (3,000 rep) to re-open them, then I encourage you to exercise that vote.
If you have that concern, but do not have that privilege, or if you think an inappropriate lock has been placed on any other question, then please raise that in a new Meta question about one Main question of concern.
Understanding a few such precedent questions (that are not "one size fits all") in detail should enable our community to adjust its close/lock policies to get the remainder "right" too.
