An alternative is to rewrite the disclaimer banner, to match the general disclaimer page in speaking of informational purposes. There are many things that might also call for clarification in that front-page disclaimer, such as "individualized advice", "qualified legal practitioner", "privileged communications" and "attorney-client relationship". If there is a reasonable chance that leaving some term undefined on that page will have a worse effect than adding a FAQ (and how do we force people to read the FAQ?) explaining what we mean by the term, then it would be a good idea.
I would favor changing "educational" to "informational" because "educational" has a very strong smell of "in the context of formal education", see for example educational software licenses (available via institutions), and to that extent, "educational" would tend to mislead people. Or, "Law SE is here to help you learn about the law".
A propos the "why" question and the alternative phrasing in the comment, why do we even say anything at all? I believe it is because not everybody has a purely academic interest in the law. Somewhere near a majority of questioners have a purely non-academic interest in solving their own specific legal issue (the other large off-topic clientele is the politic group who pose a purely political question). The wording of these disclaimers is "about" not taking things you read here to be legal advice, but the admonition that you should hire a lawyer, and the presupposition that there is such a thing as your lawyer, is itself a form of legal advice. This question, which asks "should I seek legal help" and was closed for clearly asking for specific legal advice is the first time I have seen that level of recognition that asking "what should I do" one way or the other is "asking for legal advice". So to remain consistent with the "no advice whatsoever" credo, I think we should not prejudice the decision in favor or seeking legal advice.
Therefore, "decide to seek or not to seek professional advice, based on anything you read here". Also, "ignore or heed" professional advice. I know it is controversial to say this, but sometimes legal professionals are not correct, and Law SE should not advance the stance that "your lawyer is always correct". Of course finding a palatable way to state the truly neutral status of Law SE is not trivial.
