I haven't yet consulted with the other moderators, but...
Extension development questions tend to be on the "heavier" / "more demanding" side of questions that are posted here. When a question is dumping extension requirements and does not include any coding attempt, then it is probably asking too much of volunteers.
Whenever you feel the "answer" to a problem is to recommend a book or offsite resource, there is a fair chance that the question is Too Broad or Off-topic: Requires professional hands-on involvement.
Many well-intentioned volunteers want to lead askers in the right direction, but it is more important that the questions are kept narrow so that volunteers are not abused and answers are brief and valuable to researchers. The OP on those pages doesn't have a long track record of posting here, but there is such a thing as Help Vampirism and it is generally not a good thing.
I do not mean to shame anyone who has needed support; I've been there too, in the deep end with not much to grab on to. Just keep in mind that if you are attempting to "develop an extension", then you are attempting to be a "developer". A developer should be expected to exhaustively research and try something. When becoming stuck, clearly explain where you are stuck and ask a question that gets you over the most immediate challenge. (rinse and repeat until you are successful)
Both responses at Add Options to {loadedmoduleid ID} are benevolent yet vague hints leading to directions to resources, but Stack Exchange doesn't endeavour to be a traffic controller -- it wants to be the final destination. If a question is sufficiently narrow, a concise/articulate/educational answer should be hard-written into an answer. (supplemental hyperlinks and references to resources re-enforce an answer but do not solely constitute a good answer)
When you wish to offer general guidance or resources, often writing a comment under the question is ideal. There's no real downside to doing this and you aren't likely require the special formatting that answers enjoy. You may also include in the comment that you'd like to see their efforts so you can better understand where they are stuck.
As for posting answers in the future, if you feel the urge to post redundant advice AND the two questions are not duplicates, then go out of your way to tailor your advice to be unique/specific to each question.
