Here's my take on it:

Folks still riding freewheel equipped bikes are likely older (perhaps because they're maintaining a bike that they've had for years) or are enthusiasts of the 'classic old gear'. And quite likely because they are older, they are likely more interested in finding lower gears not higher gears, hence the emphasis on the 24T, 28T 32T cogs at the other end. People do tend to slow up a tad as they age.

Looking that the 7spd 13-24 the cog selection seems reasonable. Do you honestly find you spend enough time in the 12 (or an 11?!) that the IRD design would not work for you?

I race and I only ever make into the 12 when I'm screaming along down a gradual incline with a tailwind. :-P I don't race on anything classic, but even if I did I still would rarely need a 12...
