The availability or non-availability of tagging on any platform has nothing to do with the quality or usefulness of the content. IMO, tagging is mostly useless because there needs to be a canonical dictionary of tags to choose from. That dictionary would have to be maintained by the HN mod and updated base on inputs. Otherwise every member may have a different spelling, wording, underscores or hyphens, etc.

I don’t think @dang has enough time to handle more requests and chores that add little or no value to the discussions.

I’d rather have larger fonts, an accessible interface, dark mode based on the user’s system/browser’s hints, etc. Those would make a much bigger impact for the audience.

Lastly, I’m being pedantic here: “Ask HN” cannot answer questions on HN’s implementation. Neither I nor anyone else commenting here has any clue as to why HN does not have tags or is considering adding tags in the future. Only the HN mod/admin can answer that, which can be asked by emailing them. A “Tell HN” would’ve been better to make a suggestion and get inputs.
