Somehow cricket manages to survive using three different match time formats with all three having their own merits. It is an almost direct comparison to chess, including tedious arguments about the longer form (test) dying and the shortest form (T20) not being real cricket, etc. They just put an emphasis on different skills and end up growing the game as they also have different merits as spectator and participatory sports.
Classic isn't going to die, it will probably grow, It might seem like it is dying simply because shorter time controls have far, far more potential for growth.
(The classical championship should just go back to when the champion kept the title in case of a tie. It puts more pressure on the challenger but right now it puts more pressure on whoever is worse at shorter time controls, which is far sillier.)
Having four titles of that sort would probably be a good idea. Bullet/blitz/rapid/classical. Using the internet would allow for a very inclusive yearly candidate cycle.
Plus one person holding all four would be extremely impressive.

Cricket is a good analogy. Test cricket would be the equivalent of classical chess. There is far more money now in the shorter cricket formats but Test cricket still has a significant following and is probably more popular now than 20 years ago. Professional players themselves also still consider it the true marker of skill and I think the same applies to classical chess.
Like cricket, I think the shorter formats will actually increase the popularity of classical chess as they will draw in more players and some will gravitate over time to being fans of longer time controls.
Pretty sure magnus has grinded many dead drawn positions to squeeze a win out of them. Lasker's opponents were horrible, carlsen's opponents are not, that's a big distinction.
Carlsen grinds out wins in drawn positions no doubt, but when he's able to get them because grandmaster opponents fail on basic techniques like opposition, I think they qualify as "horrible" in the end game.
Pretty sure none of lasker's opponents were even half as good as opponents carlsen has, for example none of them would even come close to caruana
