isnt the purpose of html to be a means of describing information one wishes to convey? At what point is describing the describing of information in order to describe information no longer a self perpetuating loop? I am likely naive or ignorant but isnt there little to no value, as well, to screen readers / alternate html consumers, in terms of accessibility and such? So, i guess my tl:dr is "why?"

edit: thinking deeper into this - this also conflicts with other bastardizations of html comments, used by some apparatuses (gulp initially comes to mind), which need specific, albeit semantically useless, comments as a "hook" (for lack of a better term) to distribute precompiled stuffs and such. Im not endorsing these prior bastardizations any more than I am condemning this idea, rather just pointing out that as well meaning it may have been to contrive this - to me at least, it reads as more shrapnel in a handgrenade.
