The purpose of including reconstructions in Wiktionary is not to posit them with some claim of certainty, nor is it to say “here is a theory the details of which are unilaterally agreed upon,” but rather more along the lines of “there is evidence for the existence of this, though as a reconstruction it is by nature hypothetical,” as disclaimers such as {{reconstruction}} are clear about.
I fear that you are letting your personal range of experience and particular set of opinions get in the way of constructive discussion. The theory of Altaic for one is certainly not unilaterally accepted either, nor are the particulars of the phonetics of Proto-Sino-Tibetan or Proto-Afro-Asiatic, or even Old Chinese—hell, there is still much disagreement about PIE—but in the same sense that settling on a particular phonological model for the time being shouldn't prevent Wiktionary entries for these languages from existing, neither should disagreement about families like Altaic prevent there from being any inclusion of them, as is evident already. If the assumption is that there is something inherently wrong in describing such hypotheses, what is it that is wrong? This is not a matter of whether a scholarly interest exists (it most certainly does) nor a matter of whether there is consensus among any subset of scholars working on the areas in question (there is); instead, you are in danger of now turning it into an issue of neutrality. You did not provide any rationale for the deletions either in prior discussion or retroactively (and I can only guess that your expectation was that I come to you). Other than useless deletionism I do not see any grounds for it. It is not in the same ballpark as modifying or deleting PIE paradigms in favor of alternative models: in this case your choice has been to wipe the (only) information out of existence without hesitation. Regardless, I can only hope that future incidents of this form do not take this path.
