Some points well made by Johnson and many posting here, and an important topic.
Track and field realistically depends more than other sports on the pull and value of world records. The contest matters more in the Tour de France, F1, golf or tennis majors - a great event does not need course record speeds (or their prospect), or a winner finishing always 20-under, or shooting 58s, or showing extreme Watts/kg estimates on l’Alpe d’Huez.
Field events have continued relevance because field eventers breaking records (Mondo Duplantis atm) are a commercial draw, and as much a lead on a nightly highlights package as the average Diamond League 100 or 200 metres.
For women's events, the challenges of breaking Flojo's, Koch's, Kratochvila's, et al's records stymie the profile of not only today's women, but those of the last few decades, undermining even perennial achievers and not rebalanced fully by improved shoes and tracks.
Similar if less severe issues may be involved on the men's side, though rare talents like Noah Lyles probably have more chance to make a mark (all the same, 9.58 may be a long shadow). Michael Johnson's own career and enduring legacy obviously has merit and momentum from his 19.32 breakthrough and a prolonged and successful pursuit of Butch Reynold's 400 mark. His famous race against Donovan Bailey was the clash of two world record holders, and could not be replicated right now.
In other sports, comparisons to past greats perhaps are more a curiosity or matter of trivia or fun debate, but this is less so in track and field where records are central, and when these records stand for extended periods.
Realistically there is a heavy wake that follows records and extreme marks by athletes, and indeed coaches and training groups, that are not genuinely repeatable, with risks of lost public and commercial interest at scale, and at times interference with coaches and athletes own efforts and understanding of training, and the systems they learn from.
It is not fair to say that all long-standing records are via doping issues, but the
profile of the sport does rely some way on barriers being broken, and doping legacy could form a harsh thing on that front.
Progress of training methods as well as public interest ideally would track the progress of records, but we are not there yet and maybe it would take a shift of honesty across the board (much of it retrospective re East German marks for e.g.) to get nearer.
